Mitt Romney's strong performance in the first presidential election debate has drawn him closer in the race for the White House against President Barack Obama, according to new NBC News/Wall Street Journal polls of three swing states.
In Florida, the Democratic incumbent leads his Republican challenger by 48 percent to 47 percent among likely voters. That one percentage point margin was unchanged since before the debate.

And in Ohio, Romney has trimmed two percentage points off Obama's pre-debate lead. Obama holds a 51 percent to 45 percent edge among likely voters.
All three surveys were conducted for NBC/WSJ by the Marist College Institute of Public Opinion, with margins for error of 3.1 percentage points.
In all three states, the overwhelmingly majority of voters said they'd selected a candidate before watching last week's debate. But favorable assessments of Romney ticked up in all three battlegrounds.
