(CNN) - There’s a fault line running through Wisconsin’s Democratic primary voters in early exit polls Tuesday. Nearly 6 in 10 percent of voters who support Hillary Clinton said they would be satisfied if Barack Obama was the party’s nominee; 40 percent said they would not. But the reverse doesn’t hold true: a slim majority of Obama voters said they would not be satisfied if Clinton becomes the Democratic nominee.
Likely Republican nominee John McCain, who has struggled to win over his party’s conservative base, fares better in that respect than either of his potential fall opponents: among voters who backed Mike Huckabee in Wisconsin’s GOP primary, 65 percent – - said they’d be happy to support McCain in the fall.
