(CNN) - Registered voters are split over who they will support in the next presidential election, according to a new poll. The Gallup survey released Wednesday showed 45 percent of registered voters would support President Obama and 45 percent would support a no-name Republican candidate in a hypothetical 2012 match-up.
Four percent said they would support a different candidate and six percent had no opinion. But the new figures show little change from the same survey taken in February 2010 when President Obama received support from 44 percent of registered voters and the Republican candidate received 42 percent.
Independent voters were also split on who to support. Forty-one percent said they would back Obama and 41 percent said they would back a Republican candidate. Eighteen percent would support a different candidate or were unsure.
A CNN/Opinion Research poll taken in January showed 48 percent of those surveyed would definitely or probably vote for Obama in 2012 and 51 percent would definitely or probably not. Forty-six percent of those surveyed thought Obama would win re-election in 2012, compared with the 51 percent that did not.
Gallup surveyed 1,015 adults between February 2 and February 5. The poll's overall sampling error is plus or minus four percentage points.
