Highlights from final Presidential debate

Presidential candidates John McCain and Barack Obama are back on the campaign trail Thursday following Wednesday night's third and final debate.

The final stretch of the presidential race following the last and fiery debate at Hoftsra University.

The candidates sharpened their criticism and outlined differences on nearly every issue, especially dealing with the troubled economy.

Barack Obama said, " When it comes to economic policies, essentially what you're proposing is eight more years of the same thing."

John McCain said, "I am not President Bush. If you wanted to run against President Bush, you should have run four years ago."

But it was a plumber named Joe, an Ohio voter that Obama met recently, who became symbolic of voters both candidates are courting in battleground states.

Several times, Obama and McCain referred to Joe the plumber to explain issues.

Joe Wurzelbacher said, "It was just a focal point and if it helps the debate then I'm happy for that."

With just 19 days left before the general election and early voting underway in a growing number of states, McCain has an uphill battle to turn around polls that show Obama widening his lead.

With the number of undecided voters shrinking by the day, time may be the new opponent for McCain.
