"So, why then is this man running for president, and why is he currently surging in some polls? After his fake victory he's been celebrated as the Democrats' new presidential hopeful"

As slim as his chances may be of ever winning the Presidency, right now I think that Pete Buttigieg is their best, and perhaps only hope. In my opinion, neither Bernie Sanders or Joe Biden are electable, Bernie because of his extreme left agenda, not to mention his age, and Joe because of the scandal that he and his son have been involved with in the Ukraine, not to mention of course the fact that he was Obama's VP, and did absolutely nothing to advance the Country in 8 years. As for the rest of the field, they were all non-starters from the get go. So if Pete actually does end up getting the nod from the DNC, clearly it's game over for them. President Trump will be re-elected in November without any real contest, especially if he can manage to control himself a little, and actually realize that what he says and does, will without any doubt, always be used against him at some point.
