Via email from the DNC:
On Monday, November 3rd DNC Chairman Howard Dean will spend the last full day of the 2008 presidential election helping to get out the vote for Democrats in John McCain's home state of Arizona. Dean will headline a Get Out the Vote Rally with local Democrats in Tucson, Arizona on the heels of Arizona being moved from "Leaning McCain" to "Toss Up" by Real Clear Politics.
