(CNN) - The economy was the top concern among Wisconsin Republicans, as it has been in every primary and caucus this year. But John McCain’s supporters had a competing concern in early exit polls - by a narrow 35 percent to 33 percent margin, they were more worried about the war in Iraq than the economy.

McCain’s voters made up 70 percent of those most concerned about Iraq, the polls showed, while Mike Huckabee’s voters made up 39 percent of those most concerned about the economy. Sixty-one percent of the Wisconsin GOP voters said the economy was either not good or poor.

The polls also showed that voters looking for experience tapped McCain, the four-term Arizona senator, while voters looking for a candidate that shares their values chose Huckabee.

(CNN) - Half of Wisconsin’s Republican primary voters who said they were very conservative cast their ballots for Mike Huckabee, according to early exit polls. But John McCain, who has been wooing that key GOP voting bloc, managed to pull in 40 percent of that group. Forty-nine percent of somewhat conservative Republicans went for McCain, as did 66 percent moderate voters followed suit.

Evangelical voters still flocked to Huckabee, a one-time Baptist minister.

Overall, McCain and Huckabee split the nearly two-thirds of Wisconsin Republicans who identified themselves as conservatives, with both candidates

taking 45 percent. Ron Paul, the only other Republican still in the race, drew 5 percent of the conservative vote and Mitt Romney – no longer an active candidate - drew 3 percent.

In Wisconsin, 76 percent of the GOP voters said they'd be satisfied if McCain is the GOP nominee. Forty-eight percent said McCain's positions were "about right," but 44 percent said he was "not conservative enough."

(CNN) – For Wisconsin’s Democratic primary voters, the most important quality in picking a president this year was change - and most of those voters chose Barack Obama over Hillary Clinton Tuesday, according to early exit polls.

Clinton had a narrow advantage over Obama as most qualified to be commander in chief; Obama was viewed as most likely to unite the country, improve relations with the rest of the world – and beat the Republican nominee this fall.
