If [President Obama] does not go on the offensive against ISIS...they are coming here. This is just not about Baghdad, this is just not about Syria, this is about our homeland. And if we get attacked because he has no strategy to protect us, then he will have committed a blunder for the ages.

When it comes to immigration reform, now is the time ... I've never seen a better political environment ... I'm not doing immigration reform to solve the Republican Party's political problem. I'm trying to save our nation from, I think, a shortage of labor and a catastrophic broken system.

Iran is part of the problem, not the solution. And the Russian government is ignoring reality.

In my view, Democrats and Republicans work together too little, and I would try to change that if I got to be president. And when it came to radical Islam, I would go after them before they come back here again.

We don't have enough American troops inside of Iraq to destroy ISIL any time soon.

We owe to every businessperson and worker in America the best environment in the world to create a job. We owe that to American business. 35 percent corporate tax rate is the second highest in the world. We need to lower it so they don’t leave.

I am confident - very confident - that if I help solve this problem in a way that we won't have 20 million illegal immigrants 20 years from now, not only will I get re-elected, I can look back and say I was involved in something that was important.
