President Obama put his stamp of approval on former Sen. Russ Feingold’s bid to return to the Senate, by writng an email fundraising solicitation for the Wisconsin Democrat.

“Wisconsin has a long tradition of progressivism, from Fighting Bob La Follette to the legendary Sen. Gaylord Nelson, the father of Earth Day,” Obama wrote, invoking two liberal lions from Wisconsin. “Wisconsinites are independent-minded and forward-thinking, and they’re not afraid to go against the grain.”
