Obama's charisma and youth surely helped a lot. Trump is tall and he was a good-looking young man, and his swagger has let him get away with being a total POS for 77-78 years.

Believe it or not, there are people in this world that is not immediately swayed by either waving your totem pole or burning the strawman with the opponents face. You witness a raging mob or a 100% sure fool once in your life and the magic of tribalists shouting loud being convincing, might shatter.
Those will still be swayed by emotional or other marketing tactics that appeal to their convictions, but if they managed to stay undecided in such a polar political climate like USA, my guess is that what they see are two fanatic ends of the horseshoe, and they either decides to disengage from it all or take their time to assessment which one is the lesser dummheit[1]

We only know the name of the Republican candidate at this time. You can make your decision how you want, I’ll make mine when I see who I have to decide between.
while she has admirable sympathies and even consistent policy, she has clearly demonstrated she's not opposed to pushing an agenda she does not understand.
And probably the wrong answer. I don’t see her winning over swing voters. Gretchen Whitmer seems like the best option to me. I’d enjoy watching her debate Trump.
