The race for Senate in Pennsylvania is becoming very interesting. The incumbent, Arlen Specter, is a Republican, who is being critiqued by his party for his support of the Democratic-led stimulus package last month.
According to a March 11, 2009 story in the Washington Independent, there is some chance that Pat Toomey (a long time Republican who was gone from the scene awhile, but returned with strength recently) and/or Peg Luksik (a pro-life activist and previous third party candidate) might challenge Specter in the Republican Primary.
Now, a post on The Hill suggests that Specter may be taking a step sideways. Specter says he will not run as a Democrat. Though, evidently, he is considering running as an independent. The decision will be a difficult one: Specter would have to eschew the Republican Primary altogether, since, in Pennsylvania there is a rule that if you lose in a primary, you cannot then run as an independent in that race.
