PPP's newest Colorado poll finds Barack Obama leading 49-43 in the state, just a shade closer than 49-42 when we last polled there two months ago. Obama continues to have the upper hand in Colorado because he leads with all the fastest growing groups of the electorate.
The key to Obama's lead in Colorado is Hispanic voters. They like Obama a lot, approving of him by a 66/33 margin. And they strongly dislike Romney, with only 28% rating him favorably to 69% with an unfavorable opinion. As a result Obama currently leads with them by a 2:1 margin, 58/29. Add that to Obama basically running even with whites, down only 48-47 to Romney, and it's the formula for a strong Obama standing in the state.
