Romney rolls up three wins

Mitt Romney cruised to victories Tuesday in Wisconsin, Maryland and the District of Columbia, adding to his widening delegate lead over the rest of the Republican presidential field.

Former Pennsylvania Senator Rick Santorum trailed the GOP front-runner by a wide margin in Maryland and several thousand votes in Wisconsin, after he failed to get on the ballot in the nation’s capital. Ron Paul and Newt Gingrich lagged far behind in all three primaries.

In Wisconsin, with 99% of precincts reporting, Romney led with 44%, followed by Santorum with 37%, Paul with 11% and Gingrich with 6%. With all precincts reporting in Maryland, Romney had 49%, Santorum 29%, Gingrich 11% and Paul nearly 10%. Romney took 70% of the vote in D.C.
