RACINE, Wis. (AP) -- Only a few days before Wisconsin Democrats choose their candidate to face Gov. Scott Walker in next month's historic recall election, the number of voters who haven't decided whether to support the Republican governor is tiny.

Recent polls indicate the undecided may amount to only a few percent of the electorate.

But, with the race considered a toss-up, the opposing campaigns are trying to hone arguments that will win over the wavering.

Some undecided voters say they believe Walker was too harsh in stripping public employees of their union rights, but consider the Democratic candidates uninspiring.

Others supported Walker's anti-union tactics but wonder whether someone else might do better with the economy.

The June 5 recall election is being closely watched as a national battle over union rights.
