Fortunately, the "Nader right" isn't as strong as the real Naderites. The ones who are so fanatical and ideologically pure that they defeated the Democratic candidates twice, and let W into office.
The difference being, many now realize that they traded major envirowhacko Al Gore for no-Kyoto George Bush, all for the smug moral satisfaction of voting for eco-whackjob Ralph Nader. In retrospect, Gore wasn't nearly the sellout or corporate pawn that they made him out to be. In fact, they'd have been far, far happier with him than with GW.
The people on this forum who start foaming at the mouth at the mention of Rudy are simply the right wing version of Ralph Nader supporters. They'd be happy to sink a tax cutting, tough on crime, tough on his enemies (foreign and domestic), anti-socialized medicine, pro-school choice Republican over guns, gays and abortion.
Fortunately, I think most of the "third party or none of the above" types on the right got burned badly enough by Ross Perot. Punishing GHWB only brought them Bill Clinton. It's really that simple.
Horse hockey!
We'd rather nominate a candidate that has our principles.
Your premise is based on the "only Rudy can beat Hillary" nonsense, and we're just not buying it.
