Poll: Romney favorability up slightly

Obama Romney poll vote election percent percentage chart generic
(CBS News) A new poll out Tuesday shows Republican Mitt Romney's favorability rating up slightly, although more registered voters still view President Obama more favorably. 

Following his acceptance speech at the Republican National Convention last week, 43 percent of registered voters now view Romney favorably, while 48 percent view him unfavorably, according to the Washington Post/ABC News poll. Prior to his speech, only 40 percent viewed him favorably.

Meantime, Mr. Obama's favorability numbers dropped from a peak of 54 percent in April to just 47 percent now.

The poll indicates that the decline has occurred entirely among women registered voters going from 57 percent favorable in April to 46 percent now. The poll's margin of error is +/- 4 percent.

This poll comes on the heels of a Gallup tracking poll that suggests Romney received no bump in the polls following the GOP convention.

The Gallup survey, which polled voters between August 31 and September 3, showed Romney with 46 percent support, while President Obama earned 47 percent support.

In Gallup's pre-convention tracking poll, conducted from August 24-27, Mr. Obama was at 46 percent support and Romney was at 47 percent. Both results are within the poll's margin of error, which is +/- 3 percent.
