We all understand what this is, and our energy shouldn't have to be spent on attacks against our own side by those with dubious agendas.
Then ya have the crowd here who are getting 95% of what they want. Ban on federal funding for overseas abortion, conservative judges (when the senate doesn't fillibuster), tax cuts, strong foreign policy, etc... etc... but he isn't politically pure enough.
Thinking like that is what gave us George W. Bush as president. It is called the Green voters in Florida. Michael Moore and Phil Donahue decided Gore wasn't pure enough for them, so they stumped for Nader in Florida. Now democrats hate them for it.
