Tonight we await the results of Wisconsin, Maryland, and Washington DC. Mitt Romney has large to substantial leads in polls from both states and the district. As these are winner-take-all primaries, Romney is likely to add all 95 available delegates to his current count of 572, which is already halfway to the nomination. This leaves Rick Santorum needing to win over 82 percent of the remaining delegates to be the Republican nominee. In simple terms, Santorum would have to win outright the 13 largest states remaining. However, only three of them are winner-take-all, including California, where he is less likely to win than in Massachusetts. If you assume Santorum does not win in California, he must take every delegate but nine in every remaining state to reach 1144. This race is over and you have to be Newt Gingrich or Sarah Palin to not believe it.
