A new poll shows John McCain taking a slight lead of Barack Obama in Colorado, and also shows Republican Senate candidate Bob Schafer now in a dead heat with Democratic candidate Mark Udall, who led in the same poll by 10 percentage points a month ago.

The Quinnipiac University Poll, conducted with the Wall Street Journal and, surveyed voters in Colorado, Michigan, Minnesota and Wisconsin. Of those, only Colorado went for President Bush, and it’s the only one McCain is leading it. But given that McCain just needs to hold the same states as Bush to win the electoral college, the Colorado numbers are very important. McCain led 46-44, compared with being down 5 percentage points in June.

In the other three states Obama led 46-42 in Michigan, 46-44 in Minnesota and 50-39 in Wisconsin.

The poll said McCain may be benefitting from his support for more oil drilling in the U.S. — something Obama opposes.
