Could Nebraska be the next state to select a conservative underdog in a Senate primary? Sixty-one year old Deb Fischer, a Nebraska state senator, had been a long-shot candidate for the GOP nomination for Senate against the better funded state attorney general, Jon Bruning, and the more well known state treasurer Don Stenberg.

But a poll released last week showed Fischer just four points behind Bruning, while Stenberg–who has the support of Tea Party favorites like Senators Rand Paul and Jim DeMint–had fallen back to third place. The Tea Party and conservative leaders, in fact, has been split on the candidates, with Herman Cain and Sarah Palin supporting Fischer (a fellow “Mama Grizzly”) and Bruning earning the endorsements of Senator Mike Lee of Utah and Rick Santorum.
