While I am certainly for Santorum over Casey, you can't help but see the irony here.
When fellow conservative Pat Toomey was fighting an uphill battle for the U.S. Senate in 2004, Republicans (including Santorum) worked against him. In fact, in 2004, Steve Moore wrote in National Review that "Santorum is actively working to undermine Pat Toomey's candidacy."
Of course, without conservative leaders even supporting him, Toomey narrowly lost the primary election to liberal incumbent Senator Arlen Specter. Now, just two years later, Santorum finds himself down in the polls and fighting for his political life.
I'm not gonna' call it karma, but it is ironic.
