I'm quite up-front on my blog about my support for Mark. He's a friend, and he headed up the WNY Coalition for Progress until recently. He's smart, he's got good ideas, and he's a fresh face; i.e., he's not been tainted by the political machine.
He has no ties to Joel or Nancy or any of the other folks who presided over the County's decline into fiscal crisis.
His opponent in the primary is being almost single-handedly funded by plaintiff's lawyers, and people affiliated with Steve Pigeon and Joel Giambra. Whelan is one of a very few ex-supreme court justices who was canned before retirement age. Judges are almost always reelected. Whelan must have peeved the wrong people too many times not to get the nod again. Plus, Hormoz Mansouri basically called Whalen, who was living in Florida, and invited him to run. Mansouri seems to be patently violating election law by having his myriad companies, their employees, (including employees in Wisconsin!) contribute to Whalen's effort.
So, if you like what Giambra's done for the county, go for Whalen.
If you want a new face with fresh ideas and someone who will be fiscally conservative with your money, go for Mark Poloncarz.
