We actually do need a federal government, but we need a limited one.

I think it's extremely important that the citizens of Wisconsin know the positions I'm taking.

Unlike Obama and the Senate Democrats, I respect the will of Wisconsin's voters.

Iran is Iran. It has a regime that is destabilized in the region, that is spreading terror.

We do not have a secure border on our southern flank.

All the time, you take a look at what government rules are, so you can minimize the impact of government regulations. That's just smart business.

What you don't want to do - if you're concerned about poverty, if you're concerned about providing opportunity - you don't want to rip the bottom rung of the ladder of opportunity away from people.

What happens outside of the campaign is outside of my control.

We need different perspectives here in Washington - someone who has private-sector experience, somebody who's actually created jobs, manufactures products, understands the incentives and disincentives, the intended and unintended consequences of legislation.

You turn people around, one person at a time.

When I feel there's a door open, you always walk through it.

It is past time for Congress to get serious about our spending crisis and impose fiscal restraint.

I guess when you take a look at the book 'Atlas Shrugged,' I think most people always like to identify with the main character - that would be John Galt. I guess I identify with Hank Rearden, the fella that just refused until the very end to give up.

In Wisconsin, we have got a lot of agricultural products that are exported. We have a lot of manufacturing products that are exported. I don't want to engage in a trade war.

I want to err on the side of constitutional liberty and freedom.

There are a lot of young kids serving in Washington, D.C.: kids that are smart, hard-working, but they've never farmed. They've never run a business. They've never been in the private sector. They went from high school into college and right into Washington, D.C.

I don't respect phoniness.

Donald Trump's a change agent. So am I.

People oftentimes refer to me as 'Mr. Smith Goes to Washington.' So, I'm Mr. Johnson. I'm a complete outsider.

I've been working like a dog as a United States senator.

The fairest and most democratic process in terms of Supreme Court nominees is let the American people have a voice.

I'm not a political pundit.

Career politicians manufacture hogwash.

We all have the problem of what do you do with the not-guilty-yet in free and democratic societies where you have the presumption of innocence. It's a very difficult problem.

I really don't think that the public-sector employees should be unionized.

The best way to prevent the homegrown-inspired attacks is literally positive engagement with Muslim communities. Making sure that any immigrant population that comes into America assimilates, becomes part of our culture. That has been our history; it has made us strong.

I absolutely do not believe in the science of man-caused climate change.

If you're an Islamic terrorist, probably the last program I'd use to try to get into this country is the refugee program.

Some stimulus is not a bad thing.

In 2010, there were 57 lawyers, zero manufacturers, and way too many career politicians in the United States Senate.

We are in perilous territory the stronger Iran gets. And they're getting stronger. We should make them weaker.

I have a great deal of respect for Wisconsin workers.

I am going to certainly endorse the Republican nominee, and obviously it looks like that will be Mr. Trump.

In an era of unprecedented medical innovation, we have to do more to ensure that patients facing terminal illnesses have access to potentially life-saving treatments.

As long as ISIS is not overtly losing, they'll continue to be perceived as winners.

To me, support versus endorse are two totally different things.

The core value that differentiates Apple is our ability to innovate.

There is something that happens when victims and offenders meet. Offenders and victims are able to see each other as human beings, with names and families.

I think people realize I'm truly an outsider.

I'm an accountant. I'm a manufacturer from Oshkosh, Wisconsin, who stepped up to the plate, and now I'm a U.S. senator.

Any individual that would be running for office, if they would say something that crosses a line and, in the end, is so significant, so major, that you couldn't support them, I'd have to withdraw support from any individual, okay?

Never denied climate change. It has always changed and always will.

One of the promises I made when I ran was, I'll never vote with my reelection in mind.

If you're looking for a metric that we have to measure, that we have to control, it's government in relation to the size of our economy.

You can't call ISIS the JV team. You can't say that they're contained. Sure, we've had some success, but we have not defeated them.

Innovation is this amazing intersection between someone's imagination and the reality in which they live. The problem is, many companies don't have great imagination, but their view of reality tells them that it's impossible to do what they imagine.

Trust me: our critical infrastructure is vulnerable to cyber-attack, to potential terrorist attack, and we are not taking this threat seriously enough.

When I joined the Senate in January 2011, I raised my right hand, placed my left hand on the Bible, and swore a solemn oath to support and defend the Constitution of the United States. Defending the constitutional domain of the branch of government in which I serve is an obligation of that oath.

This is nothing negative about the other candidates. It's just a recognition of the fact that Governor Romney has won more delegates. He's the only person that really has a chance to take the winning number of delegates into the convention.
