"Governor Romney's choice of Paul Ryan confirms that extremists now control the Republican Party. No member of Congress has done more to undermine bipartisanship during a time of national economic crisis than Rep. Ryan. He has vowed to end Medicare as we know it, and his budget proposal - which even Mr. Romney is attempting to distance himself from today - would slash spending for working families and balloon the national deficit through tax cuts for the highest income earners."

"With Paul Ryan on the Republican ticket, the choice facing Americans in November couldn't be clearer."
