With just one day left until election day, it looks like John McCain is holding on to Barack Obama's heels in Pennsylvania.
RCP Poll averages say Obama is leading McCain in Pennsylvania 51percent to 44 percent.
The Pew Research Center's final pre-election poll of likely voters in the U.S. finds 49 percent supporting or leaning to Obama, 42 percent for McCain; 2 precent for minor party candidates and 7 percent undecided.
When the undecided vote is allocated, Obama holds a 52 percent to 46 percent lead over McCain.
The Republican candidate has also made gains among political independents and middle-income voters.
Obama still maintains a modest lead among independents, while middle-income voters are now evenly divided.
Voter turnout is also making headlines.
