"I know that it is unusual for someone who is not a Republican to endorse a Republican candidate for President. And if this were an ordinary time and an ordinary election, I probably would not be here today. But this is no ordinary time -- and this is no ordinary election -- and John McCain is no ordinary candidate.
"In this critical election, no one should let party lines be a barrier to choosing the person we believe is best qualified to lead our nation forward. The problems that confront us are too great, the threats we face too real, and the opportunities we have too exciting for us to play partisan politics with the Presidency.
"We desperately need our next President to break through the reflexive partisanship that is poisoning our politics and stopping us from getting things done. We need a President who can reunite our country, restore faith in our government, and rebuild confidence in America's future.
"My friend John McCain is that candidate, and that is why I am so proud to be standing by his side today.
