For some background as to why Arlen Specter -- who in the past has had a pretty good record of supporting unions -- came out yesterday against EFCA, look no further than this new poll number. Specter is currently running with 27% support against winger Pat Toomey in next year's Republican primary. Remember, he only barely beat Toomey back in 2004.

Specter could probably win in the general, without too much difficulty. But the big problem is whether he can get the GOP nomination.

But by turning so dramatically on labor, which is a particularly big deal in Pennsylvania, I'm curious whether he can really make it through in the general, given the wild level of kow-towing to the right he'll need to do to secure the nomination.
