(CNN) -- With just under six months before Election Day, a new poll indicates President Barack Obama is nearly dead even with rival Mitt Romney in 12 battleground states.
Obama holds a slight two-percentage point advantage--47%-45%--over Romney among registered voters, according to the USA TODAY/Gallup Swing States Poll. The margin is well within the sampling error.
The margin is smaller than when the poll was last conducted in March, when Obama held a nine-point lead over Romney. Since then, however, two of Romney's Republican opponents -- Rick Santorum and Newt Gingrich -- dropped out of the race, paving a clear path for Romney to the GOP nomination.
The dozen states surveyed in the poll were Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin.
In terms of performance, 46% of voters said Romney would do a good job handling the economy, while 34% said the same about Obama.
The president, however, scored higher in favorability ratings, with 58% saying the president is likable and 31% describing Romney as likable.
Also notable, Democrats have made ground in the enthusiasm gap, according to the poll. For the first time in the last five battleground surveys, more Democrats (57%) than Republicans (46%) said they are extremely or very enthusiastic about voting.
The results came the same day as a Politico/George Washington University poll showed Romney with a two-percentage point margin over Obama, a difference also well within the sampling error.
For the USAToday/Gallup Poll, 951 registered voters were questioned by telephone in the 12 swing states between April 26 and May 2. The sampling error is plus or minus four percentage points.
