The Republican nomination battle is rallying Democrats behind Barack Obama. Currently, 49% of Democrats say that as they learn more about the GOP candidates, their impression of Obama is getting better. Just 36% of Democrats expressed this view in December, before the Republican primaries began.
In contrast, there has been virtually no change in Republicans’ views of the GOP field during this period. Just 26% of Republicans say their impression of the GOP field has improved as they have learned more about the candidates. That is largely unchanged from December (30%).
