Washington, Jan 7 : Voters who helped US President Barack Obama win the 2008 elections are just as excited and motivated about the 2012 presidential bid as Republicans, conservatives and tea party activists, a new survey has shown.

A Democratic-leaning pollster, Public Policy Polling found that African-Americans, Tea Party supporters and young people are the three most motivated demographic groups for the 2012 elections.

The poll found that 62 percent of black voters said they are "very excited" about voting while 55 percent of voters aged between 18 and 29 shared the same sentiment regarding the 2012 election race.

Fifty four percent of self-described liberals and self-described conservatives also admitted that they were "very excited" for the 2012 elections.

The poll also found that 54 percent of self-described Republicans as compared to 49 percent of Democrats echoed the same sentiment.

The poll found that Obama''s popularity has, however, declined among Independent voters and centrist Democrats.

"Obama''s path to reelection is difficult and if the election was today and the Republican nominee was Mitt Romney I think he''d probably lose. That''s because his standing has fallen so far with independents and with the more conservative wing of his own party. But it''s not because those core groups that fueled his victory in 2008 have lost their enthusiasm," Politico quoted PPP Director Tom Jensen, as saying. (ANI)
