Is Bernie Sanders considering a 2020 run? 'Yes, is the answer'

Bernie Sanders might be considering running for president again.

When one of Sanders' associates was asked if the 75-year-old had begun to think about another run, the associate said, "Yes, is the answer."

Even though Sanders hasn't publicly said he has plans to run again, his actions might be confirming just that.

Sanders visited Iowa, a state he narrowly lost to Hillary Clinton during the Democratic primary, and has plans to visit again to promote his new book "Bernie Sanders: Guide to Political Revolution."

He's also held campaign-style rallies in West Virginia, Kentucky and even toured across Republican-heavy states.

Sanders' campaign manager, Jeff Weaver, said Bernie Sanders is "keeping the door open" for a second White House run. The Vermont Senator is an independent, but if he does decide to run, one former campaign advisor believes he will run as a Democrat.

Some recent polls suggest Sanders and former Vice President Joe Biden would be favorites in a 2020 race against President Trump.

One associate said, "The last thing he's going to do is step aside and let Joe Biden take it."
