Internal Democratic Poll shows Walker leading 50-47%

The poll shows Walker ahead 50-47%, with a four point margin of error. The title of the article says "dead heat" which seems very misleading (couldn't it also mean that Walker's up 54-43%?), but the poll certainly shows some better news for Barrett. It also claims that Barrett's leading among independents 50-44%.

Again, this poll could be perfectly fine, but it was put out by recall supporters (We Are Wisconsin) and run by a Democratic pollster, Greenberg Quinlan Rosner Research. One other questionable moment in this poll is that the spokesman claims the other polls oversampled Republicans. If it were one poll, sure. But all three of them?
