Just a year into Joe Biden's presidency, his and Kamala Harris' low popularity and back-to-back domestic and foreign crises has Democrats searching for a viable presidential candidate.

That could set the stage for the former Secretary of State's political comeback, Douglas E. Schoen and Andrew Stein predict in a piece for the Wall Street Journal.

It all depends on how Democrats perform in this year's midterm elections, they write.

There are also mounting questions over Biden will decide to run again, given he will be 86 at the end of his second term if he wins. 

Clinton already has an edge in being younger than the sitting president, but not by much -- she would be 77 years old if she won in November 2024 and took office the following January. Biden won at the same age and was 78 when he was sworn in.  

Trump, roughly a year and a half older than Clinton, would be in a similar boat. 

'Given the likelihood that Democrats will lose control of Congress in 2022, we can anticipate that Mrs. Clinton will begin shortly after the midterms to position herself as an experienced candidate capable of leading Democrats on a new and more successful path,' the experts claim. 

Clinton's deep roots in Washington, DC as a First Lady, then US Senator, then Secretary of State alienated her to voters who craved an 'outsider' to shake up the swamp in 2016, part of the reason for her stunning loss to Trump. 

But her vast experience could be useful for Democrats seeking a 'different approach.' 

It's typically unusual for political operatives to start seeking potential candidates for the next election, especially so far out of the administration, when a member of their own party controls the White House already. It is also rare for an incumbent president to face a serious primary challenge.
