No, it doesn’t need to be changed, but supporting the Conservative cause is not an “all or nothing” proposition. That kind of thinking limits the large amount of people who may be 51% conservative to voting for democrats because they’re told by conservatives that their conservative lean doesn’t qualify them to vote conservative, because they’re somehow not conservative enough.
Several seem to feel that something about the GOP needs to change to attract those almost conservative voters, but no one has yet defined - specifically - what those changes should be. Maybe because the party really can't change anything about the pro-life, pro-traditional marriage stances without fundamentally changing the party, and alienating and losing far, far more dependable, conservative voters for some pie-in-the-sky wishful thinking about all the new voters that might be won if just a few little, hard to define things were changed.
All that navel gazing by Republicans who are uncomfortable around all those icky, conservative Christians will do little but bring more defeats to the party. The country clubbers need to learn to sell the parts of the party they do believe in more effectively, rather than trying to demean and insult the more conservative members to attract potential new voters who don't even share very basic principles.
