Did Super Tuesday Make Any Difference?

On Monday, former First Lady Barbara Bush told a conference that this year's Republicans are running "the worst campaign I've ever seen in my life." Yesterday, in ten states around the country, Republican voters told exit pollsters they were frustrated by their own candidates' attacks on each other. In six out of 10 states on Super Tuesday, Mitt Romney was the ultimate winner.  But in Virginia — where Santorum and Gingrich weren't on the ballot — Ron Paul got 41 percent of the vote, and in the big Midwest showdown in Ohio, Romney only defeated Santorum by one point. Romney still leads, but his staff is telling reporters he might not be able to sew it up before the primaries are over in June. What are yesterday's lessons for the GOP nomination and the chances against Obama in November?
