The editors of the Wall Street Journal laid out all the reasons why Mitt Romney should choose Paul Ryan as his running mate. "The case for Mr. Ryan is that he best exemplifies the nature and stakes of this election," the paper wrote on Thursday. "More than any other politician, the House Budget Chairman has defined those stakes well as a generational choice about the role of government and whether America will once again become a growth economy or sink into interest-group donimated decline." Meanwhile, Ohio Senator Rob Portman, who was once considered the most likely potential V.P. pick based on the recent changes to his Wikipedia page, now says he thinks it's more likely he'll stay in the Senate than join Romney. "I just got elected two years ago. I think that's where I'm going to end up staying," he said. "I think it's a very important position right now."
