I don't often do this, but I wanted to highlight the efforts of Progressive Kick, a group that's used a dollar-for-dollar match to raise $103K for down-ballot races. There are a couple of reasons why this is a big deal:
First, those dollars will go a lot further in smaller races. While the fundraising numbers that get national attention are measured in millions, a few thousand can make a big difference to candidates running in, say, Montana's 15th legislative district, where the delightfully-named Frosty Calf Boss Ribs won in 2008 with a warchest of $490. (She was unopposed.)
Second, In 2011 the states will redraw the boundaries of their congressional districts to account for population shifts observed in the 2010 census. In most states, the state legislature is responsible for carrying out redistricting; state legislators exercise a tremendous amount of control over what kind of candidate is electable in a given district simply by drawing its borders. Oddly-shaped districts like Trent Franks' vertical pirate ship (AZ-02) and Randy "The Neuge" Neugebauer's LEGO hook-hand (TX-19) are increasingly common these days; districts like Iowa's comfortingly regular blobs are on the wane.
In other words, control of state chambers results influences redistricting, and redistricting determines the composition of congress. The results of state races in 2010 will define the boundaries of national politics, both literally and figuratively, for a decade to come.
Tom DeLay's (R-TX) involvement in the the '02-'03 "Dancing with the Districts" scandal grew from his appreciation for the importance of redistricting and his willingness to abuse legislative arithmetic to get his way. The Republican attitude toward procedural abuse in search of political advantage has not improved since, a fact that underscores the importance of what Progressive Kick is doing on ActBlue.
