How many of these four battleground states (MN, MI, WI, CO) will Obama win?

A recent Quinnipiac poll reported by Fox News has Obama currently leading in all four of these critical states. Any of these could go either way in the election and all of them carry enough electoral votes to be worthy of a LOT of attention.

Data from the poll:

The largest gap exists with 17 percent, 54-37, of Minnesota’s 1,572 like voters preferring Obama over Republican John McCain. The margin of error was 2.5 percent.

In Michigan, 1,411 likely voters put Obama over McCain 48-42 percent, with a margin of error of 2.6 percent.

In Wisconsin, 1,537 likely voters gave Obama a 52-39 advantage over McCain, with a margin of error of 2.5 percent.

In Colorado, 1,351 likely voters gave Obama a 5 point lead over McCain, 49-44, with a margin of error of 2.7 percent.

Big leads for the Big O in Wisconsin and Minnesota with close contests in the other two. So, what will be the outcome in November?
