The Republican Party is infamous for running wing nuts for the Senate, and as a result, lost the chance for control of the US Senate in 2010.
They ran such characters as Christine O’Donnell in Delaware; Ken Buck in Colorado; Sharron Angle in Nevada; and Joe Miller in Alaska.
The first three were so whacky that the Democrats held on to the seats, and kept control of the Senate, with Harry Reid of Nevada remaining Senate Majority Leader. Lisa Murkowski won a miraculous victory in Alaska over Tea Party favored Joe Miller, keeping that seat sane and sensible, while Republican.
At the same time, Rand Paul and Mike Lee won in Kentucky and Utah, respectively, and Marco Rubio was also backed by the Tea Party, and now Paul and Rubio are likely leaders of the party in the near future, no matter how right wing they are!
Now we have in 2012 the following: Ted Cruz in Texas, backed by the Tea Party and likely to win a Senate seat; Debbie Fischer in Nebraska, who faces former Democratic Senator and Presidential seeker Bob Kerrey, who faces a tough battle; Richard Murdock, who defeated respectable conservative Richard Lugar in Indiana; and now, Todd Akin, challenging Senator Claire McCaskell in Missouri.
With the likelihood of Cruz, Fischer, and Murdock victories for the Tea Party and the right wing of the social conservatives, the only thing that may stop GOP control of the US Senate is the Todd Akin controversy, but in theory, Akin could win that race too, and with only three or four seats gain needed to win control of the Senate for the Republicans, the future makeup of the Senate is disturbing!
It should be pointed out that the Texas and Indiana seats coming up for election are already GOP seats, so only Nebraska and maybe Missouri would be gains for the Tea Party element as things stand now! But going from Kay Bailey Hutchison and Richard Lugar to Ted Cruz and Richard Murdock is a major step backward toward further deadlock, confrontation, and paralysis in a Senate already with a terrible reputation
