Exit poll: Close race in Pennsylvania, Florida

Polls have closed in two more key battleground states: Florida, the biggest battleground state in the nation, and Pennsylvania, whose 20 electoral votes Mitt Romney made a play for in the home stretch of the race.

The race is tight in both states, according to the CBS News exit poll. In Florida, men favor Romney 52 percent to 46 percent, while women favor President Obama 51 percent to 48 percent. Women are 54 percent of the electorate.

In Pennsylvania, men favor Romney 51 percent to 48 percent, while women favor Mr. Obama 53 percent to 45 percent. Women are 53 percent of the electorate.

Democrats are voting in much bigger numbers in Pennsylvania: 44 percent of voters are Democrats, compared to 36 percent Republicans. In Florida, 34 percent of voters identified as Democrats and 34 percent identified as Republicans.

In both states, independents are roughly evenly split between the two candidates.

When Florida voters were asked who would better handle Medicare, Mr. Obama leads 49 percent to 47 percent. Voters who are 65 and older are breaking for Romney 59 percent to 40 percent, and those between 50 and 64 are backing Romney 52 percent to 47 percent. More than half the electorate in Florida is over 50 years old. Almost 70 percent of Florida voters say they decided who to support before September.

In Pennsylvania, Mr. Obama has the support of three in four voters making less than $30,000. Romney has a seven-point advantage among those making $100,000 or more. Fifty-five percent say Mr. Obama is more in touch with people like them, compared to 41 percent for Romney. The president also has an edge on handling the economy: Pennsylvanians say Mr. Obama is better on the economy 52 percent to 45 percent.

This is an early exit poll and does not reflect the final exit poll results.
