That is quite understandable. Tea partiers are trying to change the norm of 50 years what the GOPe is used to and comfortable with.
If politically savvy candidates are fielded against the GOPe backed candidates, the chance of winning is good. For example Cruz & Paul. Both defeated GOPers and won in general.
It does absolutely no good to field candidates like MOurdock, AKin, O"donnell, Hoffman, etc because they lose in general to liberal democrats. Result is even worse than GOPers. That is the reality.
Todd Akin is and always has been a superb man, a superb Christian and served for years as one of our best members of Congress. His firm Christianity offended the Karl Rove/ Mike Murphy/ Mitt Romney/ Mitch McConnell/ John Boehner cabal of "GOP" quislings (the enemy within). Why Akin was not only militantly pro-life and unapologetically Christian but he even criticized NBC for filming school children saying the Pledge of Allegiance and editing out that embarrassing "under God" language that is sooooo aggravating to Muffy, Skipper, the Junior Leaguers and the polo players. Akin won a primary over other conservative candidates (no polo ponies in that race for the GOP-E to ride). He made a verbal blunder of major proportions in discussing the unlikelihood of pregnancy resulting from what he called "legitimate rape" by which he apparently meant forcible rape as opposed to statutory rape. Rove led the charge demanding his resignation from the race, the GOP-E followed suit along with the usual gang of feminazis and the desperately vulnerable Corruptocrat Claire McCaskill. Missouri can recover by defeating McCaskill in 2018 and electing a member of the reliably American and reliably conservative community. The GOP-E apparently wants Todd Akin to be the permanent poster boy for why we should nominate Muffy or Skipper for the Senate everywhere in the future even though they would generally lose in a genteel fashion more acceptable to the snobbicans. No thanks.
Mourdock defeated Richard Lugar who was about 900 years old and an abject servant of Obamaism on the Senate Foreign Relations Committee. Lugar had long deserved to be destroyed. He earned it. Law of the Sea Treaty? Panama Canal Treaty? How many more sellouts of American interests? He was a mealy-mouthed useless excuse for a Republican. Good riddance! The usual alliance of GOP-E and the Demonrats gang-raped Mourdock when he stated in a debate that pregnancy arising from rape was God's will. The winner in November was an allegedly pro-gun, allegedly pro-life Democrat Joe Donnelly, also an apparent foreign policy hawk. Indiana should come up with a solid conservative (Mike Pence?) not afflicted by foot in mouth disease to defeat Donnelly in 2018. Meanwhile, as Democrats go, Donnelly is not exactly a big problem such as Lugar always had been.
In the Delaware race, Senator Coons is leftist trash but so was Michael Castle. Christine O'Donnell was obviously not ready for prime time but Castle's House social revolutionary voting record, similar to Barney Frank, was an abject disgrace. Predictable the GOP-E jumped all over O'Donnell (having plenty of ammunition) because she had defeated the quisling Castle.
The reality is that electing trash like Lugar or Castle or Scozzafava is worse than electing Demonrats.
Bear in mind that when a Demonrat is elected, rather than a RINO/CINO, you are one election from reclaiming the seat in a straight up match against the Demonrat. If you elect a RINO/CINO Demonrat in "GOP" drag, you have to defeat the RINO/CINO and probably lose the election if you do. Then you come back a full six years after that if you are fortunate.
