Case in point is Nebraska. Although Nebraska held a caucus a while back where Obama won by a huge margin, it, like Texas and Washington, held a primary. It was yesterday. In this case, Obama BARELY won in a 49 to 47 percent squeaker.
Note this from the Omaha World-Herald:
While Obama had won 61 of Nebraska's 93 counties in the caucuses, Clinton carried most counties Tuesday, winning 63. Nearly all the counties where results flipped were in rural parts of the state.
A 4,000-vote victory margin in Douglas County was largely responsible for Obama's statewide win.
The closeness of the Nebraska primary vote does not necessarily mean Obama has seen a drop in support in the state since February, said Randall Adkins, a political science professor at the University of Nebraska at Omaha.
It's more a reflection on the difference between caucuses and a primary, Adkins said.
You better believe there is a difference, and it has to do with gaming the system.
