Donald Trump actually said...

"The absolute best way to win and to beat the Democrats and very easily, I think, beat the Democrats no matter who it may be, whether it's Hillary or anybody else."

"I think it's somewhat ridiculous but that's okay."

"The best way for Republicans to win is if I win the nomination and go directly against whoever they happen to put up, and for that reason I have signed the pledge."

"I will know more about it than you know, and believe me, it won't take me long."
