With the nomination of Solicitor General Elena Kagan to the Supreme Court, many are highlighting a political pitfall for one then-Republican senator who opposed her appointment to her current job. 

Sen. Arlen Specter (D-Pa.) -- who was still a Republican when the Senate voted to confirm Kagan as solicitor general in March of last year -- joined 30 other GOPers in opposing her nomination.


The Pennsylvania senator chaired the Judiciary Committee until 2007. 

Specter faces a stiff primary challenge this year from Rep. Joe Sestak (D-Pa.) The congressman has questioned Specter's identity as a "true Democrat," saying that he switched parties purely for political gain. 

Democratic voters will go to the polls in just over a week and Specter's leads in the polls have dissipated, many show the two candidates are statistically tied. 

The centrist senator has said that he switched parties because he saw an easier path for reelection, and also because the Republican Party strayed too far to the right. 

Seven Republican senators backed Kagan for solicitor general: Tom Coburn (Okla.), Susan Collins (Maine), Judd Gregg (N.H.), Orrin Hatch (Utah), Jon Kyl (Ariz.), Richard Lugar (Ind.) and Olympia Snowe (Maine).
