Romney over Obama in Gallup Tracking Poll...

...of registered voters.

Romney took 47 percent support from surveyed registered voters, while Obama took 45 in a poll conducted between April 11 and April 15. Romney's edge, though, is within the poll's three-point margin of error.

Independents tipped the scale in favor of Romney, going for the former Massachusetts governor 45 percent to 39.

The Gallup poll backs up a Rasmussen poll from last week that at the time looked like an outlier. The Rasmussen poll showed Obama and Romney tied at 45 percent, but was the first to show such a tight national race after a number of polls in March showed the president stretching his lead to double digits.

That's registered voters, not likely voters. Polls of likely voters typically favor Republicans. So, figure that the polling that Obama has shows that he's already way down.
