Wisconsin primary expected to be close for Dems.

Senators Barack Obama and Hillary Clinton are locked in battle for delegates in Wisconsin as both try to gain momentum to be the standard bearer for the democratic party. Both candidates are close in delegate count but Obama has won the last eight states giving him a significant momentum advantage. Hillary's firewall is expected to be on March 4th with delegate rich Ohio and Texas.
Senator John McCain is expected to lock up the nomination soon as he is coming close to the 1191 delegates needed for the republican endorsement. Former President George Bush endorsed McCain in Texas signaling that party leaders are ready to wrap this thing up. While Huckabee remains in the race he is scene as a long shot and would be statistically difficult to overcome McCains lead.
