So sparse is the field of possible Democratic challengers to Gov. Scott Walker next year that this is garnering attention in political circles:

Milwaukee businessman Andy Gronik — a political neophyte with no statewide name recognition — recently paid for a lengthy poll to help him decide whether to take on the Republican governor in his 2018 re-election bid.

Two individuals contacted by the pollster earlier this month said they were asked to compare Gronik with two other Democrats, state Sen. Kathleen Vinehout of Alma and Dane County Executive Joe Parisi, who bowed out of the race this week. The poll did not ask about state Rep. Dana Wachs of Eau Claire or Jefferson County District Attorney Susan Happ, two other Dems who might run.

Gronik's poll also asked a number of questions about Act 10, the Republican governor's signature piece of legislation that curtailed collective bargaining for most public employees, and Wisconsin's private school voucher program.
