The results of the latest poll from Quinnipiac University:
MICHIGAN: Obama 48 - McCain 44
MINNESOTA: Obama 47 - McCain 45
WISCONSIN: Obama 49 - McCain 42
From the poll press release:
By 19-24 point margins, voters in Colorado, Michigan, Minnesota and Wisconsin say Democrat Barack Obama, not Republican John McCain, is the candidate of change, helping lift Sen. Obama into the lead in these battleground states, according to four simultaneous Quinnipiac University polls of likely voters in these battleground states, conducted in partnership with The Wall Street Journal and washingtonpost.com and released today.
More voters in each state also would rather see Democratic vice presidential candidate Sen. Joseph Biden become President, even though voters in each state say Sen. McCain's selection of Gov. Sarah Palin as running mate is a good choice.
Sen. Obama has double-digit leads among women in every state except Minnesota, where his six-point lead leaves him with only a two-point edge among all voters.
