Democrat Bob Casey, the State Treasurer of Pennsylvania and a putative Santorum-slayer, has been bringing home the bacon... and upstaging one of his biggest boosters in the process.

Casey announced today that his campaign committee has raised $1.89 million for the quarter, setting a new record for a Democratic Senate challenger taking on a Republican incumbent. This comes on the heels of a new Quinnipiac poll, released yesterday, which gave Casey a double-digit lead over Rick Santorum.

So whose record did Casey break? The reigning cash champ had raised $1.5 million in the first half of 1997. His name was Chuck Schumer, and he was the one who convinced Casey to run in the first place.
