We need a consistent conservative, someone who has stood for free market principles, who has stood for the Constitution and, critically, who stood for the working men and women of this country.

I think too many politicians are not listening to the men and women they represent, and if we're going to change the path America is on, we have got to be fighting for policies not that benefit the giant corporations and the banks and the special interests and the lobbyists, which is what Washington focuses on every day, but instead every policy needs to focus on the working men and women, the truck drivers and the steelworkers, and the young people.
