Looks like a big night for Romney

Cable anchors will be breathlessly waiting for the polls to close tonight, but don't expect too many surprises. The online trading site Intrade gives Romney a strong chance of winning Ohio, North Dakota, and Alaska, and he's a virtual lock in Virginia, Massachusetts, Vermont, and Idaho. Give Georgia to Gingrich and Tennessee and Oklahoma to Santorum. At this point, Romney has an 87.9 percent chance of winning the nomination, according to the Intrade line - and Intrade has been pretty reliable. By the way, President Obama now has a 60 percent chance of being reelected.
