GOP Has a Shot as Long Held Dem Seats

That's what happens in wave elections:

Rep. David Obey has won 21 straight races, easily prevailing through wars and economic crises that have spanned presidencies from Nixon to Obama. Yet the discontent with Washington surging through politics is now threatening not only his seat but Democratic control of Congress.

Obey is one of nearly a dozen well-established House Democrats who are bracing for something they rarely face: serious competition. Their predicament is the latest sign of distress for their party and underlines why Republicans are confident of big gains in November, and perhaps even winning back the House.

The fight for the midterm elections is not confined to traditional battlegrounds, where Republicans and Democrats often swap seats every few cycles. In the Senate, Democrats are struggling to hold on to, among others, seats once held by President Barack Obama and Vice President Joe Biden. Democrats are preparing to lose as many as 30 House seats - including a wave of first-term members - and Republicans have expanded their sights to places where political challenges seldom develop.

"It's not a lifetime appointment," said Sean Duffy, a Republican district attorney here in the north woods of Wisconsin, where he has established himself as one of the most aggressive challengers to Obey since the Democrat went to Washington in 1969. "There are changes in this country going on and people aren't happy."

There's more at the link. Lots of Dems who felt pretty good about their long-term employment prospects are punching up their resumes these days.
