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.

I saw the government really using the excuse of a weak economy and a financial crisis to create more government and to push onto the American entrepreneurial society more and more restraints and government activity.

The reality is that until we can agree on a formula that reduces tariffs globally we cannot meet this Doha promise for development. In order to keep momentum post-Hong Kong, the European Union must be willing to move.

Things are not getting better. They are getting worse. We need to elect Mitt Romney to turn things around.

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.

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.

I think what people are looking for right now is not the kind of pizzazz and pop that perhaps we thought we got in 2008. Certainly, President Obama offered that. What they want now is someone who can work closely with Congress and get things done.
