Another liberal group came out in support of Sen. Kirsten Gillibrand’s 2010 Senate bid on Tuesday, though this one could cut both ways with voters.

The Association of Community Organizers for Reform Now Political Action Committee, also known as ACORN, endorsed Gillibrand for New York Senate, calling her “a leader who will always fight for those who have been pushed to the brink in this economic crisis.”

ACORN, which fights for policies that benefit low-income and working class people, has been dogged by controversy for its voter registration tactics in the 2008 campaign. But that hasn’t scared away Democrats, who, like Gillibrand, still seek out its support and organizing clout.
