There are similarities with 1994 except in the other direction, naturally. The key difference, though, is the Internet. Lots of grass roots Democratic organizations are having a real effect but the two biggest ones, in my opinion, are MoveOn and Progressive Democrats Of America. I donate money to both regularly and monitor their work closely in order to remain comfortable with my how my contributions are utilized. I am very happy thus far.
These groups are doing for the left what Jerry Falwell and Pat Robertson did for the right in 1994 but even more effectively. They are doing it mostly online and in 4 key ways:
1) The mobilize staff and supporters to bring their message right into Congressional offices.
2) They organize grassroots media events and protests at the local level all around the country in a way this nation hasn't seen since the run-up to the invasion of Iraq.
3) They convince political outsiders to run for elected office at the local, state and national level
and then educate those candidates on how to win.
4) They endorse candidates through a strict screening process and then cross pollinate with those endorsees to help raise money and volunteer man hours to put them in office.
And they’re just getting started!
