Most conservatives doubted that McCain had a prayer of winning the general election. If he does win the general, it will be because chaos reigned in the Dem primary and both candidates were weakened.
We were going to have Hillary and/or Obama anyway. What Rush, and others, are doing is giving McCain the opportunity to take advantage of his nomination victory, go out and make the most of the money on which he has to campaign, get out his message, and gain support while Hillary and Obama are each spending their money fighting one another and trying to win their primary nomination.
If the strategy works, we’ll have President McCain. If it doesn’t work, we’ll have a socialist Dem doing all of the things you mentioned, just as we would have gotten had the strategy never been tried.
If Hillary and/or Obama is elected it would tend to be more despite the strategy than because of it. OTOH, if McCain manages to win the presidency, he would owe a debt of gratitude to the conservatives who helped him achieve it...not that he would feel indebted or do anything to thank them, of course.
I think it is fruitless for conservatives to allow the frustration we feel to turn us against one another because of differing opinions on how to make the best of a bad situation.
