Could third parties take advantage of next year's US Congressional elections?

is Cindy Sheehan running?

lol running to be the superminority leader in the house. i doubt she'll so much as garner a handful in san francisco. she's riding on the hopes that dems are frustrated with pelosi's inability to end the war but im pretty sure a majority of dems especially those in her district understand that the bush vetoes and the slim majority take the main blame, not the party itself. either way it's sheehan's race to lose
