(CNN) - Election Day is still days away, but Republicans are already caught up in a heated debate about Sarah Palin's future role in the party should the GOP ticket fail to win the White House.
In one corner are some conservatives who believe the Alaska governor has been a detriment to John McCain's presidential bid and threatens to lead the party astray for the foreseeable future.
Another faction says Palin's core-conservative beliefs, demonstrated political acumen, and compelling frontier biography position her to reshape the face of a party now viewed by many voters as out of touch.
It's a debate,somewhat ugly at times, that is beginning to play out in public view as Republicans brace themselves for the possibility of losing the White House and a significant number of seats in Congress come Election Day. And that may leave the party in shambles with drastically reduced influence in Washington.
Should that happen, political observers say, the party will face its biggest identity crisis in more than a generation, and Palin may well be caught squarely in the middle of it.
"A civil war that is simmering will break out into the open if McCain loses, and the party will have to decide what they want to be in the post-Reagan world," said Gloria Borger, a senior political analyst for CNN.
