He's nice and all, but can we go back to electing Presidents who have had lots of executive and political experience ?
But he's not just nice.. He's pretty, played in a band, and is exceptionally good at hand waving. In debate he masterfully dodges substantive discussion in favor of vast, inclusive, amorphous nicety rhetoric. Unfortunately however, he may be too white and male to appease his party's intersectional hierarchy.
Given that the top two Democratic candidates for 2020 by current polling are Joe Biden and Bernie Sanders, I don't think there's much reason to think that being white or male is a huge disadvantage.
His thin resume, OTOH...
