Sen. Hillary Clinton's slim loss in Nebraska's primary this week has brought down some pressure on the state's superdelegates to switch their across-the-board support for Sen. Barack Obama.

Obama had trounced Clinton in Nebraska's February caucuses where Obama picked up 68 percent of the vote. But in the non-binding primary, Obama eked out a win with 49 percent of the vote to Clinton's 47 percent. Clinton supporters claim that shows Obama's support is dwindling.

Superdelegate Kathleen Fahey said she has been receiving a flurry of e-mails from voters who say they will not vote for Obama in the general election. She said she thinks the letters are being mass mailed to superdelegates.

"I just hit ‘delete,' ‘delete', ‘delete'," Fahey said. "This will not affect my vote."

Obama has won 16 of Nebraska's 24 delegates and has the support of all six of the state's superdelegates.
