Absolutely.
But if the set of unifying principles includes anything other than "we want to win elections," then it detracts from the primary purpose of a political party, which is to win elections.
I hope not. Elections are a means to an end. Republicans could adopt centrist/Democratic ideas and win elections, but for what? ****, that's what Democrats do, and so now we have Obama: gays still can't serve in the military (nor can prominent Dems openly support discrimination-free marriage), warrantless wiretapping shall continue, the climate bill is a mess, Gitmo has not been closed down, we'll surge in Afghanistan, oh, and he's not even trying for universal health care.
But not to the idiots in the RNC who value ideological purity over the ability to win elections. If you want a group of unelectable wing-nuts, the Libertarian party is over there
... unless you want to win elections, in which case I'm afraid it does.
Barry Goldwater's campaign failed, but his ideas proved more successful in the longer, ideological struggle. Just the other day I saw a poll that said less than half respondents think we should ban assault weapons. In the mid-90s more than 3/4 said we should ban such weapons. Public opinion is not static. Moreover, conservatives don't need to be popular to win as they enjoy so many institutional advantages: the undemocratic Senate is like affirmative action for small states; the Electoral College inflates their influence as well. Also, the classic thinking is that a higher voter turnout helps Democrats; Republicans are more tribal, more unified, and more committed. We have almost never had more Republicans than Democrats (I think I heard it reported that the GOP claimed more registrants shortly after 9/11, but that's since gone away).
Yes, Republicans are in danger of becoming a southern party. As Tricky says, it's in everyone's interests to have competitive elections (otherwise you get the kind of Democrats we have in Sacramento), but it's not like these ten points will put Republicans out. If unemployment continues to rise, Afghanistan continues to worsen, Republicans can continue denying evolution, global warming, and everything else, it won't matter. The advice Democrats in this thread are giving Republicans is not unlike the advice Republicans were giving Democrats six years ago.

The party purity test that you addressed in your first response does indeed make sense, particularly if there are multiple parties to choose from. While there are more than the two majors, the numbers three to n are so small as to be nearly irrelevant. This condition forces the two majors to grasp for the "sorta excluded middle," a voter pool who need some courting to choose one way or the other. That courting might also result in repulsion, but that's the risk one takes when one asks the girl to the dance.
In keeping with my above post, the Republican strategy has long been to use wedge issues to appeal to single-minded voters: abortion, teh gays, affirmative action, illegal immigration, gun control.
