A YouGov/Yahoo News poll published last week found support for President Joe Biden and former President Donald Trump to be tied at 44%. This was a major change from August when an earlier poll gave Biden a six-point lead.

Meanwhile, other surveys even show Trump as having a slight lead. Given these facts, some observers are predicting that Democrats will scramble to replace Biden ahead of election day. 

Ted Cruz says Michelle Obama is "the most likely" replacement for Biden

One of them is Texas Republican Sen. Cruz, who suggested during a recent episode of his podcast "Verdict with Ted Cruz" that former First Lady Michelle Obama could take the president's place as nominee.

"Here's the scenario that I think is perhaps the most likely and most dangerous," Cruz told his listeners. "In August of 2024, the Democrat kingmakers [will] jettison Joe Biden and parachute in Michelle Obama."

NEW: Senator Ted Cruz believes Biden will *not* be the 2024 Democrat candidate & thinks the Democrats will "parachute" in... wait for it...

Michelle Obama.

"And so when I see the media turning on Joe Biden right now, I think the odds of Michelle Obama parachuting in in August of 2024 have risen dramatically and that ought to scare the hell out at anyone who is unhappy about the direction this country is going," he continued.

Poll shows two thirds of Democrats think Biden is too old

"Michelle Obama because she was the first lady has the ability to parachute in above all four and say, 'Hey, we're not picking among any of you. You guys can all fight it out next time, you're all on the same level. We're coming,'" Cruz said.

"This is the Obamas coming in and saving the day," he declared, adding, "And I think in terms of a solution that unifies Democrats, there ain't nothing like that."

Cruz is not the only one who sees a potential opening for Mrs. Obama, as conservative filmmaker Ami Horowitz expressed similar thoughts to Sky News Australia earlier this month.

Horowitz cited a NORC Center for Public Affairs Research survey from August which found that roughly two-thirds of Democrats see President Joe Biden as being too old to serve another term in office.

Gavin Newsom could be another contender

Michelle Obama is not the person who has been named a possible replacement for Biden, however, as others have pointed to California Democratic Gov. Gavin Newsom.

"If the president were not to run, it’s hard to imagine that Newsom would not be sorely tempted to enter the race," Fox News quoted former Obama advisor David Axelrod as telling The New York Times in June.

"Newsom is young and politically muscular, which may be just what the market will be seeking post-Biden," he added.
