Why just the Dems? I dislike both parties but find myself hating Republicans a little less than Democrats -- mostly for fiscal reasons. I've got to believe there are similar people in both parties that are fed-up with what the government has become.
If you ask me, both parties need 'agents' like you're talking about. People that are rational and don't party-line vote. Take each issue into consideration. Dragging the leftists/rightists to the middle to actually discuss items in a civil manner -- total consideration for the citizens that elected their asses.
I fear this country is toast within 50 years if we can't get away from bipartisanship and party line votes.
