As Obama is becoming a bit more active in the news, i would say that this would be the ultimate wrestling showdown.
I think Trump would win because he's bigger than Obama.
The only one who can challenge Trump on his 3rd run is Obama because the Dems have nobody else.
Obama's tactic would be 'divide and conquer while giving a worldwide apology tour' while Trump's tactic would be the one he's using now.
MOVE!
