ABC and the Washington Post have just released the results of their joint tracking poll, showing Mitt Romney with a 1-point lead over Barack Obama. If that sounds close, consider that those are the rounded numbers; it’s actually closer.

The poll, which sampled 1,382 likely voters, was conducted Friday through Monday, before last night’s third and final presidential debate. The margin of error is plus or minus 3 percent.

Romney has the edge with likely voters on his command of the economy. Is it the economy again, stupid? Focus groups consulted after last night’s foreign policy debate certainly seemed to think so.

The breakdown of the sample gives Democrats a +5 advantage: 34 percent of respondents consider themselves Democrats, 29 percent Republican and 33 percent Independent. That’s right: Independents outnumbered Republicans in the survey sample.

Has Romnesia had any adverse side effects on Mittmentum? It doesn’t look like it.
