Who is the odd one out and why ... ?

Bush. Obama screwed the country, and Clinton screwed anything that moved.

Bush because he's the only one who's father was also president

Obama because he didnt send troops into war?

Bush, the only republican

They're all odd. Both Obama and Bush are trying for first base with Clinton (Bush with the drop down tactic and Obama with the reach around)... and Clinton's enjoying it.

The guy on the left, he's wearing sunglasses :O)

Bush, cause hes not an atheist

Clinton never had a trillion dollar deficit..

lol probably Obama.
The other two had their integrity questioned repeatedly

Bush he's the republican

Bush, he's the only Republican

Wowwww.... Hah! 😁

Bush.

The (meaningless) Iraq War will be his legacy.
