At the debate, Donald Trump backed off of his health care position for 20 years. For 20 years, he has agreed with Hillary Clinton and Bernie Sanders on socialized medicine, saying Obamacare doesn't go far enough. He wants the government to pay for everyone's health care and to control it.

If you want to beat Donald Trump, you know, one of the clearest indications of who can beat Trump is Donald spends every waking moment attacking me. He doesn't attack any other candidates, because his campaign views us as the only real threat to him.

For anyone who doesn't believe that Donald Trump is the best candidate to go head to head with Hillary Clinton in November, and that's about 70 percent of Republicans nationwide who don't think Donald Trump is the right guy, our [President's] campaign is the only campaign that has beaten Donald Trump and that can beat Donald Trump.

What data can tell you is if you have 10 messages, all of which you believe, it can tell you which messages are resonating and which aren't. And if you break it down even further, the truth of the matter is some messages resonate one place and other messages resonate another place.

I will happily support anything that protects life.
