Politico ... "Forecast for Dem primaries: Ugly"

“It’s going to be beyond ugly,” said Terry Madonna, director of the Franklin and Marshall College poll, speaking to the tone of the May primary. “I think it’s going to be at a level that’s virtually unprecedented.”

The race Madonna was speaking to Politico.com about is in Pennsylvania where Republican turncoat Arlen Specter has stiff competition from a fellow Democrat.

It's turbulent political waters out there ... and Democrats are facing a "sweep them out" mentality across the nation after passing financially backbreaking legislation in the first nine months of Barack Obama's administration.

However, they are also faced with challenges from within the Party as cash-cow MoveOn.org raises its head:

Some in the party privately worry that it might come to that in several states, including one that isn’t even on the radar at the moment. In what was widely perceived as a warning shot to Sen. Blanche Lincoln, an Arkansas Democrat facing a difficult 2010 reelection, the progressive group MoveOn.org announced earlier this month that it has raised $3.5 million to fund a primary to any Senate Democrat who votes against the health care bill.
...
Asked if MoveOn’s threat was a problem for the party, [a senior Democratic] strategist responded: “[Expletive] yes.”

Republicans had better roll up their sleeves and get to work because 2010 going to be a long and rocky campaign season.
