“Kapaka lost in his 2010 congressional race by almost 4%. He won the Senate seat in 2008 by 3% (~ 2500 votes).”
You mean Kapanke? He is currently a state senator. How did he run for Congress in 2010, if he got elected to the state senate then?
Kapanke was elected to the state senate in 2008 for a four year term. In 2010, he unsuccessfully ran for US Congress without giving up his seat. The only people facing recall are state senators elected in 2008, a legislator has to be in office for one calendar year before he can face recall.
Running for higher office didn't mean he had to give up his Senate seat.
He was the GOP nominee for House of Representatives vs Ron Kind (D) RAT bastard socialist demoRAT who votes solid liberal and somehow portrays himself as moderate and enough of the ignorant voters buy it. In any case, Kapanke campaigned largely in the Nov 2010 for the House seat, but still ran for his current WI state senate seat.
