(Denny Crane: "Sometimes you can only look for answers from God and failing that... and Fox News".)
You failed then. We all did.
Until Rush and the rest of the pundits admit this, conservatives will not only not get the nominees they want, they'll come off as losers who couldn't even get their #1 priority accomplished, and then failed to recognize the core problem when the sheet hit the fan.
Not focusing on the core problem hurts conservatives much much more than the GOP.
If people are as fed up as you say, then why are they sending the Senators who got them fed up in the first place, back to the Senate? The problem isn't Miers' lack of a record. The problem is there are a lack of a Conservative voice in the Senate to push the Conservative agenda through the Senate, without turning tail and hightailing it to the tallgrass when Kennedy, Schumer, and Clinton ask for floor time. Because that's exactly what the Republicans did last time around when Bush was pushing nominees through the judicial process. Another problem is, too few people pay any attention to the clowns that represent them, no matter what party that clown belongs to.
Conservatism as YOU know it, failed. Conservatism will continue to fail until such time it acknowledges the problem and deals with it accordingly, rather than just adding to the problem at hand, and continually being "fed up".
You can vote third party if you want. That won't solve things in the long run. Voting third party is rooted in shortsightedness.
