High risk:
Randy Hopper (Fond du Lac) won by only 163 votes in 2008. I'd call that one at very serious risk.
Alberta Darling (River Hills) won by 1% in 2008, just over 1,000 votes. I'd call that one at serious risk.
Some risk:
Dan Kapake (La Crosse) won reelection by less than 3% in 2008, about 2500 votes, slightly smaller margin than when he took the seat. He ran for congress in 2010 and lost by almost 4%. I'd say there's some risk to this seat.
Little risk:
Sheila Harsdorf (River Falls) won by 12% in 2008, over 11,000 votes. Probably safe.
No risk:
Rob Cowles (Allouez) won with 99.35% of the vote. I think he's safe.
Luther Olseon (Ripon) won with 99.35% of the vote. I think he's safe too.
bump for later...
