Considering the source isn’t credible, and considering Democrats are still hiding, it’s dubious.

From Salon:
There has been a frustrating lack of credible, independent polling data on the standoff over public employee unions in Wisconsin, which exploded into a national story late last week. So we still don’t have a clear sense of where voters stand on Gov. Scott Walker’s push to strip public sector workers of their collective bargaining rights.
But there is a new survey making the rounds that suggests a backlash may be stirring, with 52 percent of respondents opposing Walker’s plan and 61 percent expressing a favorable view of public employees (compared with just 39 percent for the governor). Of course, the data comes with a catch: It’s from a poll commissioned by labor and conducted by a Democratic firm (one that has a knack for coming up with results that are agreeable to Democrats but somewhat at odds with reality). So take it with a grain of salt.
