Obama Increases Lead Nationally

A new NBC News/Wall Street Journal poll finds President Obama leads Mitt Romney nationally among likely voters, 50% to 45%.

Key finding: Obama and Romney are tied, 43% to 43%, on which candidate would do better on the economy.

Said pollster Peter Hart: “Simply put, if Romney doesn’t win on dealing with the economy, he doesn’t win.”

The survey also gives Obama his highest job approval since March at 50%.
