We are seeing Republicans uniting behind this [presidential] campaign [2016].

Socialism has been an abject failure across the face of the globe, millions have suffered under socialism, and yet we're not doing an effective job communicating that.

I think what Republicans want is someone who will stand up and lead, who will take on the great challenges of the day, who will make the case that the path we're on isn't working; that the Obama-economy is a disaster, that Obamacare is a trainwreck, that our constitutional rights are under assault and that we need to restore America's leadership in the world.

Using overwhelming air power to utterly and completely destroy ISIS. To put things in perspective, in the first Persian Gulf War, we launched roughly 1,100 air attacks a day. We carpet bombed them for 36 days, saturation bombing, after which our troops went in and in a day and a half mopped up what was left of the Iraqi army.

Obama has been the most lawless president we've ever had.
