Obama 4, Clinton 0

With a clean sweep of today's 4 contests (Louisiana, Washington, Nebraska and the Virgin Islands) and heavily favored in next week's primaries, Obama could have a very strong showing for February.

Clinton's team has been counting on holding him back with the early March primaries in Ohio and Texas.

She's currently favored in both, but if Obama generates momentum from his victories, both states could become very competitive. Clinton ads are expected to go on the air in Ohio in the coming week.

In such a scenario, it makes the few remaining primaries, which include Kentucky and West Virginia, of even greater importance.

So it's a very real possibility that the Tri-State may play a major role in determining a party's nomination for the first time in a generation.
