The problem is that this round from its inception has had agriculture at its centerpiece. The EU and the U. S. and other WTO members cannot wish that away, that is a reality.

That isn't how I've always felt. As a congressman, and more recently as a senator, I opposed marriage for same-sex couples. Then something happened that led me to think through my position in a much deeper way.

My concern about Barack Obama is he ran a campaign in 2008 where he said we're going to bring people together and solve big problems. And he specifically talked about the need to reach across the aisle and deal with issues like the economy, which was obviously the top issue in 2008. It has not happened.

Instead of focusing on growing jobs and reigniting our economy, President Obama focused on growing government and tried to remake the United States into the image of the debt-laden countries of Europe. His approach has been more spending, more regulation, and higher taxes.

If you start very far to the left, it's harder to get to the middle.

President Obama has been attacking relentlessly. In 2008 he said that if you're out of fresh ideas you use stale tactics against your opponent - you try and make your opponent unacceptable and that's what he is trying to do.

There has never been a campaign where there hasn't been sniping from the outside and second-guessing. I hear the same sometimes from the Democratic side in terms of President Obama's campaign, so that's to be expected.
