Polls show a very close race, with a slight edge overall to Obama, but within the margin of error.
Some commentators have speculated that, seemingly paradoxically, Obama might do well, both in states with the higher African American populations, and also in some with very low percentages of black residents. In the former, because of expectations for record-high African American turnout, and in the latter, because they lack some of the racial animosity of states with more racial balance. If he wins Colorado, it will, of course, be in that second category.
But, as of now, Colorado is a toss-up.
