ISIS is gaining strength because the perception is that they're winning. And President [Barack] Obama fuels that perception.

It is my hope that all of the Republicans who recognize that nominating a candidate who agrees with Hillary Clinton on a host of issues, who has a very similar record, is not the path to victory. And if we come together, if conservatives stand together, we're going to have a great night on Tuesday.

I hope that we have a culture that values every human life from the moment of conception to the moment of natural death.

You would carpet bomb where ISIS is, not a city, but the location of the troops. You use air power directed - and you have embedded special forces to direction the air power. But the object isn't to level a city. The object is to kill the ISIS terrorists.

One of the most troubling aspects of the Rubio-Schumer Gang of Eight Bill was that it gave President [Barack] Obama blanket authority to admit refugees, including Syrian refugees without mandating any background checks whatsoever. Now we've seen what happened in San Bernardino. When you are letting people in, when the FBI can't vet them, it puts American citizens at risk.

If you want a candidate who is led the fight against Obamacare, who will lift the burdens on small businesses and bring back jobs, I'm the only candidate in the race with that proven record.

It's critical to have a sound foundation in free-market economics and the Constitution. A great many Republicans in Washington don't have that foundation.
