Sens. John McCain and Barack Obama both rolled through the Potomac region primaries, picking up the District of Columbia, Maryland and Virginia all in convincing fashion.

Obama has much to be excited about, as he is now leading rival Sen. Hillary Clinton in the democratic delegate total.

"The change we seek swept through Chesapeake and over the Potomac," Obama told supporters at a Wisconsin rally after results of today's primaries became public.

"We won the state of Maryland. We won the commonwealth of Virginia. And though we won in Washington, D.C., this movement won't stop until there is change in Washington, D.C, and tonight we're on our way," Obama continued.

On the GOP side, McCain believes that he has officially put himself out of Gov. Mike Huckabee's reach, and is now looking ahead to the general election this fall.

"We do not yet know for certain who will have the honor of being the Democratic Party's nominee for president. But we know where either of their candidates will lead this country, and we dare not let them," McCain said to a group of supporters in Virginia.

"They will promise a new approach to governing, but offer only the policies of a political orthodoxy that insists the solution to government's failures is to simply make it bigger," McCain continued.

District of Columbia

McCain defeated Huckabee soundly with 68 percent of the vote to Huckabee's 17 percent. The victory gives him all 16 of the state's delegates, and moves him closer to 1,191 necessary to pick up the nomination.

Obama picked up the District in an equally impressive manner, finishing with 75 percent of the vote to Hillary's 24 percent.

The victory will give him at least nine delegates, while Clinton should pick up at least one. 

Maryland

Since inclimate weather stifled voter turnout early in the day, judges moved the closing of precincts to 9:30 EST. 

With 55 percent of the Republican vote to Huckabee's 30 percent, McCain's strong day only gained steam when the delayed results from Maryland began to pour in.

For the first time this primary season, McCain drew more support from regular church attendees than Huckabee, with 45 percent from those that attend weekly to Huckabee's 42 percent.

McCain led his opponent throughout the state, winning suburban Baltimore, District of Columbia suburbs and the remainder of the state all by at least 22 percent.

We won the state of Maryland. We won the commonwealth of Virginia. And though we won in Washington, D.C., this movement won't stop until there is change in Washington, D.C. Sen. Barack Obama

Obama's victory in the state was equally impressive. He picked up 60 percent of the vote to Clinton's 37 percent.

Perhaps the most surprising finding from exit polls is that Obama picked up 55 percent of the female vote to Clinton's 41 percent. Until recent primaries, Clinton had controlled that demographic.

Like McCain, Obama won convincingly throughout the state, winning Baltimore city, suburban Baltimore, District of Columbia suburbs and the rest of the state by as much as 41 percent.

Obama also had a commanding lead in almost every other demographic.

Virginia

On the Republican side, McCain was again victorious but by a significantly smaller margin.  McCain's 50 percent support edged out Huckabee's 41 percent and McCain came away with the final southern state's 60 delegates.

As in earlier primaries, Huckabee picked up the majority of his support from protestants that attend church regularly. 60 percent of evangelical Christians supported Huckabee to McCain's 31 percent.

Northern Virginia, which accounted for 24 percent of the state's total vote, gave McCain the victory. He took 60 percent of the vote in the region to Huckabee's 29 percent.

For the democrats, Obama defeated Clinton 64 to 35 percent.

As in Maryland, Obama picked significantly amount of support from both male and female voters, a trend that could be ominous for the Clinton campaign.

Women voters were 21 percent more likely to vote for Obama than Clinton. Obama won almost every other demographic.

Look Ahead 

Primary voting will resume on Feb. 19 when Hawaii, Washington and Wisconsin will all take to the voting booths. Obama is heavily favored in all three of the states and is currently campaigning in Madison, Wis.

Clinton has opted to focus her campaign efforts in Texas and Ohio, rather than next week's primary states. 

With McCain's resounding victories today, Huckabee would need to win 85 percent of the remaining delegates to be tied for the Republican nomination, though he is in a virtual dead heat with McCain in Washington and Wisconsin according to Rasmussen polls.
