Trump is not the most self aware guy...look at how he has repeatedly denies saying things  after he's been recorded saying them... he's  blatant about that sort of lying...

I think that he was simply foolish/blind  enough to think that these women wouldn't come up...he left himself totally wide open with his "I only talked about it, Bill did it..." justification...and that is the sort of statement you'd want make only  if you're absolutely  sure that it is true...he hasn't shown that sort of insight...

I don't know what he was thinking...he boasted of being a bigger hound dog than Clinton and its hard to imagine him thinking that  wouldn't come back on him....except he's managed to get away with a lot among his fact free followers and he was blind to it........

His stupidity in leaving himself open like he did is reason #568 why she shouldn't be president...
