Presidential hopefuls cast their ballots

A record number of voters are expected to take to the polls this Election Day, and joining that tally were the candidates themselves.
Sen. Barack Obama, (D-Ill.) along with his wife and daughters, cast his vote in Chicago Tuesday. Obama summed up his past two years by saying, "The journey ends, but voting with my daughters, that was a big deal."
On the Republican side, Arizona Sen. John McCain and his wife Cindy voted in Phoenix.
It is still anyone's race, however, exit polls show Obama with a significant lead.
