Election analyst says Sanders could have more staying power than Biden in 2020

Election analyst Kyle Kondik told Hill.TV's "Rising" on Friday that Sen. Bernie SandersBernie SandersBullock: I would not have endorsed health care for undocumented immigrants on debate stage Harris faces pressure to define policy proposals Biden campaign rips 'Medicare for All,' calls on Dems to protect Affordable Care Act MORE (I-Vt.) will likely have more staying power in the 2020 race than Joe BidenJoe BidenHarris faces pressure to define policy proposals Biden campaign rips 'Medicare for All,' calls on Dems to protect Affordable Care Act Harris voices support for Puerto Rico protesters: 'I stand with them' MORE if the former vice president launches another White House bid.

"I guess the thought is that Biden is almost like a balloon and that once he actually becomes a candidate, the balloon punctures and all of these things come out about him," Kondik, managing editor of the political website Sabato's Crystal Ball, told hosts Buck Sexton and Krystal Ball. "But maybe that's not true, maybe he does have staying power."

"I think Sanders may have more staying power because I think at least he has an established base he can bring from 2016 that he can bring with him," he said. 

"Even if his so-called floor is 20-25 percent, a lot of people were saying that about Donald TrumpDonald John TrumpLiz Cheney: 'Send her back' chant 'inappropriate' but not about race, gender Booker: Trump is 'worse than a racist' Top Democrat insists country hasn't moved on from Mueller MORE in 2016, too, and that floor kept going up, and no one was able to pull a lot of support from him," Kondik added. "If Sanders is to win the nomination, maybe that's how it will work for him, too."

Polls have shown Sanders and Biden leading the crowded Democratic field for 2020.

A Quinnipiac University poll released last week found that 29 percent of registered Democrats surveyed said they supported Biden, while 19 percent backed Sanders.

However, Biden has been dealing with allegations this past week that he has inappropriately touched multiple women at public events.

The former vice president released a video on Wednesday in which he vowed to be more mindful of women's personal space going forward.
