U.S. Democratic Party presidential candidate Barack Obama will most probably continue his good streak and do well in the three Mid-Atlantic primaries scheduled for Tuesday.

Senator Hillary Clinton is the underdog in the contests scheduled for today in Washington D.C. and the states of Maryland and Virginia. The voter turnout is expected to be high in these states were Barack Obama seems to be the top favorite as he and Clinton clash for the 168 pledged convention delegates at stake in the voting.

Obama, 46, has easily won four weekend contests in Maine, Louisiana, Nebraska and Washington, thus slightly surpassing Clinton in the competition for pledged delegates who select a party nominee. However, the latest delegate count estimates show Clinton with a slight lead over Obama - at least 1,147 to Obama's approximately 1,120.

For the Republicans, frontrunner John McCain looks forward to regain some momentum after loosing the recent rounds to former Arkansas Governor Mike Huckabee. However, the latter is way behind the veteran Arizona lawmaker when it comes to delegates needed to secure the party nomination.

Clinton is already looking past today’s voting in anticipation of the primaries scheduled for March 4 in the states of Texas and Ohio. Recent polls showed that democratic senator has the edge there.

The Democratic Party needs 2025 delegates to ensure a presidential nomination, while the Republican Party needs only 1,191.

Polls are set to end at 7 p.m. EST in Virginia and at 8 p.m. EST on Wednesday in Maryland and the District. The results will be released soon afterward.
