Sorry, but a weird-named gay mayor of some town most people have never heard of would get steamrolled by Trump
Maybe if the election were tomorrow, but you do know he'd have a whole general election to campaign and get exposure, right? Not to mention BRTD's point where >45% of the country would easily vote for anyone against Trump.
You don't have to get less than 45% of the vote to be steamrolled. if Buttigieg only got around that, Trump would flip Minnesota, New Hampshire, Nevada, and ME-AL from 2016.
