Recent daily tracking poll averages nationwide put President Obama at 47% and Romney at 46%, according to Gallup.

"We have been monitoring the potential impact of the Republican convention on the presidential race on a day-by-day basis," writes Gallup's editor-in-chief Frank Newport. "So far, we don't see an impact."

Newport also noted that "both Obama and Romney for the most part have been at or around 46% since we began tracking in April."

In a separate post, Gallup cited a new poll showing that last week's convention in Tampa "had a minimal impact on Americans' self-reported voting intentions, with just about as many saying the convention made them less likely to vote for Mitt Romney as say it made them more likely to vote for him."

Gallup will soon start assessing the impact of the Democratic convention that starts Tuesday in North Carolina.
