Turns out the 'suppression' was really by polling firms who didn't like the results they were getting:
“We did a poll last weekend in Colorado Senate District 3 and found that voters intended to recall Angela Giron by a 12 point margin, 54/42. In a district that Barack Obama won by almost 20 points I figured there was no way that could be right and made a rare decision not to release the poll. It turns out we should have had more faith in our numbers,” pollster Tom Jensen wrote in a post on the firm’s website Wednesday.So they chose not to believe the (accurate) results because it didn't fit their political agenda. Since they didn't believe it, it didn't get into the media which we all know would have tried to bury the story anyway. So PPP isn't a 'polling firm', it is a propaganda mill for the Democrat party.
