(CBS) - Election Day is now just 4 weeks away and the race for the White House is tighter than ever.
Both Mitt Romney and President Obama will campaign in Ohio today. It's a key battleground state that many believe could make or break victory for either candidate. In a Pew Research Center poll last month, Romney trailed President Obama by eight points... 51 percent to 43.
But a Pew poll taken after the presidential debate last week shows Romney ahead now by four points, 49 percent to 45.
Remember, today is your last day to register to vote in the November General Election.
