Barack Obama 52
John McCain 42
With the Hispanic vote unifying behind him, Barack Obama is out to his largest lead yet in a PPP poll of Colorado.
Obama is now leading 71-21 with that group of voters, a considerable improvement from a 57-36 edge in PPP's survey of the state taken three weeks ago. The white vote is exactly the same as it was previously, a 48-47 advantage for Obama. Obama's margin has increased by three points since that poll, which showed him with a 51-44 advantage in the state.
The economy may be helping to drive Obama's gains. Three weeks ago 51% of voters in the state listed it as their biggest concern. That number has now spiked up to 60%. Among those folks Obama's lead is 60-34.
Colorado also provides a clear example of how Sarah Palin's popularity across the country continues to fall. Right after the GOP convention her favorability was 41/38. Three weeks later it was 38/47. Now it's dropped to 36/49.
The numbers paint a picture that shows it nearly impossible for McCain to win the state at this point. Only 6% of voters are undecided, and among those who do have a preference currently only 6% say there's any chance they could change their mind. Obama's lead at this point is such that McCain would have to win virtually every undecided, keep everyone who could change their mind currently supporting him in his camp, and win over almost 100% of current Obama supporters who say they aren't totally committed to him. The chances of all those things happening? Not very good.
