Neither one of these surveys comes from a top-flight pollster and the methodology of each one has been questioned by pros. Healthy skepticism of the results is warranted.
I’m giving them to you anyway. For one thing, we’re starved for high-quality state polls at the moment due to the coronavirus epidemic. In a normal world we’d have multiple reliable surveys of a marquee Senate race like Cory Gardner versus John Hickenlooper over the past six weeks, but the people who staff phone banks at polling outfits are coping with the same lockdown problems the rest of us are. That leaves us more dependent on online-only surveys, which may skew towards better educated and higher-income voters. And those voters trend Democratic, which means the numbers for Team Blue may be inflated. But for now, they’ll have to do.
For another thing, the results in both polls are strikingly similar, suggesting that they may not be wildly off from the true state of play in Colorado. And they jibe with the only other poll of the Colorado Senate race, which was taken last year and showed Hickenlooper with a double-digit lead over Gardner. It’s conceivable that we’re headed for a landslide there, with Trump and the NRSC potentially not even bothering to contest the state. If that’s true then the Democrats’ likely win in CO would cancel out the Democrats’ likely loss of Doug Jones’s seat in Alabama. They’d need just three more pick-ups plus a Biden victory to have total control of government.
