What exactly is the logic here? Democratic primary voters are growing disenchanted with the 76 year-old white, centrist front runner, so seizing on this perceived opening, the 77 year-old white, centrist man is going to try to fill the void?
Agree with this. However, at least his brain is working properly, unlike Biden's. (On the other side, he is far less charismatic than Biden, and has almost no working class appeal I reckon, unlike Biden.) I do think he could chop substantially into Biden's coalition however, because Biden's coalition is so broad. He won't get Biden's African Americans or working class, but he could get a considerable chunk of his retiree and moderate supporters, including never Trump Republicans and independents.
