What is the reason a person might run for President?

1) The person might genuinely be interested in pushing the boundaries of the discussion about what is possible so as to bring that more closely in line with what is moral.

Sen. Bernie Sanders introduced his most sweeping plan yet to tackle the increasing cost of a higher education, introducing a bill Monday that would make public colleges and trade schools tuition free and cancel outstanding student loan debt for everyone, a proposal that goes beyond one introduced earlier this year by one of his chief presidential campaign rivals, Sen. Elizabeth Warren.

2) ¯\_(ツ)_/¯

(CNN)In an already-crowded primary field, former Pennsylvania Rep. Joe Sestak became the latest Democratic candidate to wade into the race for the presidency, announcing his candidacy in a video posted to his website Sunday morning.

Sestak, who mounted unsuccessful bids for US Senate in 2010 and 2016 touted his "commitment to service," citing his career in the US Navy, where he rose to the rank of 3-star Admiral.  

Is Mitch Landrieu still thinking about it?  I know he said he would defer to Biden but we all expect Biden is going to cancel himself any day now.
