Ivanka Trump Won't Challenge Marco Rubio, But Speculation Remains About Trumps' Ambition

Ivanka Trump has ruled out challenging Senator Marco Rubio (R-FL) for his seat in the Senate in 2022. The decision follows some speculation that former President Donald Trump's daughter would seek to replace Rubio.

Trump reportedly spoke to the Republican senator in recent weeks and told him she would not mount a campaign against him. However, she has not formally ruled out a future run for any other elected office.

"Ivanka offered her support for Marco's reelection and they had a great talk," a spokesperson for Rubio said, according to Politico. They could also appear together at an event.

The former first daughter's decision will reignite speculation about the Trump family's political future.

Her brother, Donald Trump Jr., is seen as a possible presidential candidate in 2024. He remains a popular figure in the Republican Party and unlike his father, he still has access to social media.

Twitter and Facebook played a major role in propelling the former president to the GOP nomination in 2016. He was initially thought of as an outsider candidate but his campaign's use of social media, combined with significant attention from traditional news outlets, helped him get ahead of rivals.

And it's the former president himself who remains the favorite to win his party's 2024 nomination. A Politico/Morning Consult poll showed that 54 percent of Republicans wanted Trump to be the candidate, with former Vice President Mike Pence trailing a distant second at just 12 percent support. In the same poll, Donald Trump Jr. won 6 percent.

Trump could run again and win reelection to a second term in 2024. As the Senate voted to acquit him, he has not been barred from holding federal office. However, only one defeated president has ever returned and won a second non-consecutive term: Grover Cleveland in 1892.

There has been less speculation about Trump's other adult children, Eric and Tiffany, but senior members of the administration have emerged as possible presidential candidates.

Former U.S. ambassador to the United Nations Nikki Haley is widely seen as a strong contender. Her recent criticism of Trump was seen by some as an indication that she will be his main rival in the next GOP presidential primaries, if he runs.

Former Secretary of State Mike Pompeo is another possible candidate. Unlike Haley, he was not publicly broken with Trump and he's previously suggested on Twitter that he's interested in a run. However, he won just 2 percent support among Republicans in the Politico/Morning Consult poll, while Haley won 6 percent.
