Currently, the United States has troops in dozens of countries and is actively fighting in Iraq, Syria, Libya, and Yemen (with the occasional drone strike in Pakistan). In addition, the United States is pledged to defend 28 countries in NATO. It is unwise to expand the monetary and military obligations of the United States given the burden of our $20 trillion debt.

What gets lost is that the Republican Party has always been the party of civil rights and voting rights.

I think that if you believe in regime change, you're mistaken. In 2013, we put 600 tons of weapons - us, Saudi Arabia, and Qatar - into the war against [Bashar] Assad. By pushing Assad back, we did create a safe space.

The Bill of Rights existed long before President Obama was elected, and as long as I’m a U.S. Senator, I will fight to protect the basic rights and liberties that belong to all of us as American citizens.

You can see why there are more people wanting to come from economically-distressed areas, and they can't all come to America. So it gets into the valid, legitimate debate over immigration as to how do we choose. Do we have a diversity lottery and take people from everywhere, do we base it more on merit?

You don't go into politics unless you want to win.

You shouldn't have one opinion when you're running and another when you're president.
