Vice President Joe Biden swooped into Detroit yesterday for some political fundraising, and of course, a chili dog at Lafayette Coney Island.

The back-to-back fundraisers held at the MGM Grand Detroit Casino for U.S. Reps. Gary Peters of Bloomfield Township and Mark Schauer of Battle Creek were a high-dollar success — netting an estimated $318,000 combined.

In 2010, first-term Democrats Peters and Schauer are expected to be targeted by the GOP.

But both seem well on their way to boasting well-funded reelection campaigns — Peters’ campaign reported $1.1 million in cash at the end of the third quarter, while Schauer’s campaign reported $900,000.

According to CQ Politics, Schauer’s 7th Congressional District leans Democratic while Peters’ 9th Congressional is rated as likely Democratic.
