"PAC for a Change is
kicking off our 2008 "Choose a Challenger" contest –- an opportunity
for you and our entire online community to decide which Democratic
Senate Challenger our PAC will support next.  The winner of our online
contest will be featured in a fundraising email to our PAC for a Change
community, potentially adding tens of
thousands of dollars to his or her campaign war chest this fall --
going a long way towards helping us build a stronger progressive Senate
majority in 2009 and beyond.

Go fill out the ballot adding tens of
thousands of dollars to his or her campaign war chest this fall --
