The Washington, D.C. primary results are expected to produce a win for former Massachusetts Gov. Mitt Romney on Tuesday night.
Former U.S. Sen. Rick Santorum did not meet the qualifications to appear on the ballot in the nation's capital. The Wisconsin primary and Maryland primary are taking place the same day.
HuffPost's Mark Blumenthal reports:
Thus, at a minimum, Romney appears likely to win 80 of the 95 delegates up for grabs on Tuesday. Coupled with a symbolically powerful sweep of all three contests, the night should be sweet for the Romney campaign.
