MILWAUKEE -

Voters participating in the Wisconsin recall election are about evenly divided on the changes made to collective bargaining for state government workers.

Preliminary exit polls conducted Tuesday for The Associated Press show that about half of voters said they approve of the changes while half disapprove.

About 4 in 10 on each side said they feel that way strongly.

About half of voters said they have a favorable opinion of unions for government workers. Just over 4 in 10 view them unfavorably.

The vast majority of voters think recall elections should be allowed in at least some cases, though most feel they are appropriate only in cases of official misconduct.
