With the big unity mission in Unity, New Hampshire tomorrow, some good news for the Democrats.

As Hillary Clinton and Barack Obama come together to campaign for the common cause, Obama is actually leading John McCain in polls from four battle ground states.

According to surveys conducted by Quinnipiac University for washingtonpost.com, here are the latest swing states results:

Obama leads McCain among Democrats and Independents in Michigan, Colorado, Minnesota and Wisconsin.

If Obama wins these four states and the traditionally Democratic states, it will be simple for the Democrats to take back the White House in November.

The Quinnipiac also shows Obama leading McCain by double digits while other polls, such as the Gallup daily tracking poll, show the race to be much tighter.
