Even with only 15 percent of precincts reporting, Mitt Romney had more than 48 percent of the vote in Maryland Tuesday night.
Second-place candidate Rick Santorum came in with 29 percent at Daily Universe presstime with Newt Gingrich pulling 11 percent and Ron Paul eight percent.
Maryland is a winner-take-all state, where the candidate with the most votes takes all delegates. Should the polls continue to add up as they have, Romney will find himself 37 delegates closer to winning the nomination.
Romney had 42 percent of the vote in Wisconsin, with 11 percent of precincts reporting. Santorum had 38 percent. In Washington D.C., with 28 percent of precincts reporting, Romney had gathered 69 percent of the vote.
According to the Associated Press, Romney is predicted to sweep all three primaries.
'We need someone who understands what liberty is all about,' Santorum said in his speech in Pennsylvania on Tuesday night. 'If we're going to win this race, we can't have little differences between our nominee and President Obama.'
Santorum said he has every intention of continuing in the race and winning Texas at the end of May.
'Let's not make the mistake of 1976 again,' Santorum continued, referring to the Republican loss to the Democratic nominee. 'Let's move straight to 1980 and defeat the incumbent president.'
Romney is just as determined, however, and with a much stronger lead, only improved his chances in the Tuesday's primaries.
Rep. Paul Ryan recently endorsed Romney's campaign and introduced him to Wisconsin voters Tuesday night.
'Thank you to Wisconsin, Maryland and Washington, D.C.,' Romney said in Wisconsin Tuesday night. 'We won a great victory tonight in our campaign to restore the promise of America.'
