Debunking the Bradley Effect

With Barack Obama having moved into a statistically significant lead in most public polling, and the Democrats' strongest issue—the economy—likely to remain tops on the electorate's mind between now and Nov. 4, commentators are asking how John McCain can win the election. The best answer that many of them have come up with? The "Bradley effect."

The Bradley effect is named after Tom Bradley, the former Los Angeles mayor who, in 1982, narrowly lost a bid to become California's governor after having led substantially in the polls. The same pattern reflected itself in other instances involving African-American candidates: Douglas Wilder underperformed his polling in 1989 (but still narrowly won the Virginia governor's race), as did David Dinkins in the New York mayoral race that same year. The theory goes that, in these races, white voters wanted to appear politically correct by telling pollsters they were going to vote for a black candidate when, in fact, they were not prepared to do so.

Will Obama be the next victim? I say no. Examples like Bradley and Wilder are nearly a quarter of a century old, and there's no proof that the Bradley effect still exists.

Take the recent study by Harvard fellow Daniel Hopkins, who examined the performances of African-American candidates in major electoral races from the 1980s through the present day. Hopkins found that the Bradley effect did exist during the '80s and early '90s. But it dissipated sometime thereafter; recent black candidates like Deval Patrick and Harold Ford Jr. have performed almost exactly as their polls predicted ahead of time. Hopkins theorized that this was because many hot-button racial issues, like crime and welfare, had been taken off the table by the centrist reforms of the Clinton administration.

Then there are this year's primaries. Everyone remembers New Hampshire, when nearly all polls predicted a big win for Obama, but Hillary Clinton emerged victorious. That was a bad day for the pollsters—and for Obama, who underperformed the Pollster.com composite average by 9 points. (Still, it is not clear that there was evidence of the Bradley effect at work here. Contributing factors to Obama's loss may have included his "nice enough" comment, Senator Clinton's teary moment in the diner—and a simultaneous GOP primary, which allowed McCain to pick off some Obama voters who thought their guy was safely ahead.) What fewer remember is what happened two weeks later in South Carolina. In that case, the Pollster projection had Obama winning by 15 points—but he won by 29. That 14-point error was actually of greater magnitude than the mistake in New Hampshire, if less noticeable because the polls hadn't picked the wrong horse.

South Carolina was not the only state in which Obama overperformed his polls. They significantly underestimated Obama's margin in essentially every Southern state, including Virginia, Georgia and North Carolina, as well as a couple of states outside the South, like Wisconsin, Indiana and Oregon. On balance, the polling during the primaries underestimated Obama's support by 3.3 points when compared to the Pollster averages in those states. And yet, a belief in the Bradley effect persists. Why? People are confusing voters exhibiting racist behavior with voters lying about their intentions to pollsters.

    The problem with Obama is a simple one. One association does not a radical make. But in Obama's case, the list of left-wing radical mentors and associates is seemingly endless, (Davis, Ayers, Wright, Khalidi , etc., etc.) with a new revelation practically every day. With that trend, a picture begins to emerge, and that picture is that Obama is as steeped, not in just left-wing political thought, but in radical left-wing economic and race ideology, to the same extent that Pat Robertson was steeped in the ideology of the radical Religious Right. I would not have voted for Pat Robertson for dog catcher, and for similar reasons, I will not vote for Obama.

    The Wall Street crisis was planned the night of Obama's meeting at Bill Ayres home to put Obama in The White House. Together they put a beautiful plan into place.

    This Strategy was first elucidated in the 1966 issue of 'The Nation' Magazine by a pair of radical Socialist Columbia University professors, Richard Andrew Cloward and Frances Fox Piven.

    David Horowitz summarizes it as:

    "The strategy of forcing political change through an orchestrated crisis. The "Cloward-Piven Strategy" seeks to hasten the fall of Capitalism by overloading the Government bureaucracy with a flood of impossible demands, thus pushing society into crisis and economic collapse.

    Obama begin with ACORN by funneling millions into their organization. He then trained ACORN to stage protests in banks to force them to issue risky loans or they would be threatened to face racial charges. ACORN was trained to intimidate financial institutions into giving ???Ninja??? loans to people with NO assets, NO job and NO income, who couldn???t afford these loans.

    That caused the housing bubble two years ago it was by ACORN's actions they were able to destroy our credit system.

    As this played out, D-Barney Frank and D-Chris Dodd were able to cover up the millions of improvident loans to these bad risky house buyers. And Barney Frank and his chums successfully were able to block all of President Bush's attempts to put a rein on this problem.

    So Fannie & Freddie was forced to purchase all these failed subprime mortgages.

    Then both Frank and Dodd denied that there were any problems, and refused the Bush Admin. requests to set up a regulatory agency to watch over Fannie Mae and Freddie Mac, and they were still pushing for these agencies to go even further in promoting sub-prime mortgage loans almost up to the 'minute they failed'.

    Democrats then blamed Bush saying it happened on his watch knowing it would hurt the Republican Party in the election setting it up that Barack Obama could use this to his advantage.

    Karl Marx once compared a Revolutionary struggle with the work of the mole, who sometimes burrows so far beneath the ground that he leaves no trace of his movement on the surface.

    Barack Obama is that Marxist mole !

    Kelo v. City of New London, 545 U.S. 469 (2005),
    What does redistributive mean. Well, remember that it was the liberal Left-Wing Justices of the U.S. Supreme Court that brought us this little jewel, holding that the government could take your real property, like your home, not for public use like a road or school, but to give to another private individual, such as a political contributor or other party hack or interest group.
    Kelo v. City of New London, 545 U.S. 469 (2005), was a case decided by the Supreme Court of the United States involving the use of eminent domain to transfer land from one private owner to another to further economic development. The case arose from the condemnation by New London, Connecticut, of privately owned real property so that it could be used as part of a comprehensive redevelopment plan. The Court held in a 5-4 decision that the general benefits a community enjoyed from economic growth qualified such redevelopment plans as a permissible "public use" under the Takings Clause of the Fifth Amendment. Justice John Paul Stevens wrote the majority opinion; he was joined by Justices Anthony Kennedy, David Souter, Ruth Bader Ginsburg and Stephen Breyer
    The decision was widely criticized by American politicians and the general public. Many members of the general public viewed the outcome as a gross violation of property rights and as a misinterpretation of the Fifth Amendment, the consequence of which would be to benefit large corporations at the expense of individual homeowners and local communities. Some in the legal profession construe the public's outrage as being directed not at the interpretation of legal principles involved in the case, but at the broad moral principles of the general outcome.
