Another big night for Mitt Romney: He won the night's primaries in Wisconsin, Maryland, and Washington, DC, reports CNN and AP, a trifecta that should push him past the halfway point in the race for the magic number of 1,144 delegates. Newt Gingrich and Ron Paul finished well back in the two states, though Paul might pick up a second-place finish in DC, where Santorum was not on the ballot.
