States won by Barack Obama (dark blue) and Hillary Clinton (light blue) as of 2/10/2008

After this weekend’s impressive wins in every state (and the Virgin Islands) that held a primary or caucus, Barack Obama is riding a wave of momentum while Hillary Clinton’s campaign appears to be in disarray. After today’s big win for Obama in Maine (where Obama was behind in the polls), the Clinton campaign stole the headlines - but not in a good way. The Clinton campaign announced tonight that its campaign manager had been replaced.

To date, Barack Obama has won 19 states to Hillary Clinton’s 10. Increasingly the map appears to be filling in for Obama. He is also now ahead in the number of pledged delegates. With a fundraising edge and rising in the polls, Barack Obama heads to the Beltway Primaries this Tuesday when Maryland, Virginia and the District of Columbia will hold their primaries. Obama is expected to handily carry both Maryland and DC.

Virginia is considered the state where Clinton may be able to slow Obama’s momentum. However, a series of polls over the last few days show Obama with significant leads in Virginia. The latest Mason-Dixon poll has Obama up by 16 points (Obama 53%, Clinton 37%). The latest Rasmussen poll has Obama ahead by 18 points (Obama 55%, Clinton 37%). The latest SurveyUSA poll has Obama ahead by 20 points (Obama 59%, Clinton 39%). A poll taken by InsidersAdvantage also shows Obama with a 15 point lead (Obama 52%, Clinton 37%).

The numbers inside the polls also show Obama with significant advantages in Virginia. Both the Rasmussen and SurveyUSA polls show that Obama is even with Clinton amongst white voters in Virginia, while the Mason-Dixon poll shows Clinton leading amongst white voters (there is no demographic breakdowns in the InsidersAdvantage poll).  All polls have Obama leading by wide margins amongst Black voters in Virginia. In the SurveyUSA poll, Obama leads amongst men and women, and all age groups except those over 65. Clinton still leads Obama amongst Hispanics, although the margin is shrinking. The SurveyUSA poll also shows Obama winning in every region of Virginia except the rural Shanandoahs to the Southwest. If the polls hold up, Obama is headed for a big win in Virginia this Tuesday.

If Obama takes the three primaries this Tuesday and wins the remainder of the contests in February, as he is likely to do, Hillary Clinton’s campaign will be reeling by the time the March 4th primaries in Texas and Ohio are held. Although the most recent polls show Clinton ahead in Ohio and Texas, both states are likely to tighten by the end of this month. With a bigger war chest and the momentum Obama will continue to gain in the polls. If he wins throughout February it is quite likely Ohio will move into the Obama column (a la Missouri). The Clinton campaign is now hoping to survive until March 4th and hold the line in Ohio and Texas. But as Rudy Giuliani’s experience in Florida showed, a string of losses can be debilitating. The early leads in the polls tend to evaporate as the other candidate keeps racking up wins.

Hillary Clinton’s campaign relied very much on the air of inevitability. She was supposed to have the Democratic nomination sewn up by Super Tuesday. However, that inevitability was demolished by Obama’s strong showing last week. Now it is a horserace in which Barack Obama caught up and is now pulling away. The conventional wisdom is that the race is so close that it may go all the way to the Democratic National Convention. However, a long string of losses for Hillary Clinton in February will drastically change the media buzz. Tuesday night, if Barack Obama has a big night (and that means winning Virginia), the headlines about the "neck and neck" race will suddenly change. The money may then begin to dry up and the superdelegates may start to move toward the frontrunner. If that happens this race is over.
