Congressman Paul Ryan will be Mitt Romney's running mate. This election is about values, and today Romney doubled down on his commitment to take our country back to the failed policies of the past.

Ryan is best known as the author of a budget so radical The New York Times called it "the most extreme budget plan passed by a House of Congress in modern times." With Romney's support, Ryan would end Medicare as we know it and slash the investments we need to keep our economy growing -- all while cutting taxes for those at the very top.

Now is not the time to go back to using top-down economic policies that caused our economy to crash. Barack Obama and Joe Biden know that to rebuild our economy, we have to strengthen the middle class.

I stand with President Barack Obama and Vice President Joe Biden because they are the team with the right ideas to help us build an economy that is built to last. Paul Ryan and Mitt Romney want to go back to using top-down economic policies that caused our economy to fail in the first place.
