Not really sure why there is an argument against validating signatures. The process shouldn't be tainted by fraud.
Will there still be enough valid ones? I would hope the recallers could find 500k valid signatures, considering 1.1 million people voted against walker in the last election.
I'm sure by the time the recall election will roll around, both sides will have plenty of "evidence" to support their claims. Recallers will argue that Walker cost them their jobs, while supporters will argue that Walker saved their jobs.
Same ****, different day.
