Rasmussen's latest poll is out--with Udall up 9 points over Schaffer, 49-40.
Rocky Mountain Right has an updated poll tracker.
Quick key points (I'll have more later)--the Secretary of State is now two months behind on updating voter registration numbers for Colorado. With both candidates at 84% of support from their respective parties, it is clear that the battle for independents will decide the race, and this is where Udall's support has grown dramatically. He now leads 51-30, up from 45-33 last month. Though he has still not gone above the rather significant 50% threshold (with undecideds still lurking out there, and most from the much needed independents), Udall's polling strength is clear. Political tailwinds and heavy liberal attack ad buys early on are definitely playing a role, as is the fact that the Democrats' Presidential nominee is known.
The effects of the Democratic National Convention won't be known until September, the debates are still in limbo, and with just under 5 months to go, polling data is still nothing to bet the farm on--just ask the formerly presumptive Democrat nominee, Hillary Clinton.
