After a long drumroll, Sen. Arlen Specter finally has the long-threatened 2010 primary fight.

Former Rep. Pat Toomey sent out a news release this morning announcing that he has posted a videtaped message on his campaign web site.

“If Pennsylvania’s senior senator stood up for taxpayers and job creation – instead of routinely voting against taxpayer interests – I would feel less compelled to run. Unfortunately, he does not,” says Toomey.
