How can we tell when Trump is engaging in strategic lying and when he's not?
I see what you've done here.
Very elementary Dr Watson!
Trump has zero need to attack Obama because he is not running against Obama in 2016. If Trump says something nice about Hillary & Bill in the prelude to the primaries, get back to me.
In the meanwhile Trump needs to steal as many Obama voters as he can, away from Hillary. This dude has common sense coming out of his ears.
