Sarah Palin's favorability rating is 10 points higher than Joe Biden's; she edges out Obama and McCain by one point. Rasmussen reports:

A week ago, most Americans had never heard of Alaska Governor Sarah Palin. Now, following a Vice Presidential acceptance speech viewed live by more than 40 million people, Palin is viewed favorably by 58% of American voters. The latest Rasmussen Reports national telephone survey finds that 37% hold an unfavorable view of the self-described hockey mom.

The figures include 40% with a Very Favorable opinion of Palin and 18% with a Very Unfavorable view (full demographic crosstabs are available for Premium Members). Before her acceptance speech, Palin was viewed favorably by 52%. A week ago, 67% had never heard of her.

The new data also shows significant increases in the number who say McCain made the right choice and the number who say Palin is ready to be President. Generally, John McCain’s choice of Palin earns slightly better reviews than Barack Obama’s choice of Joe Biden.

Perhaps most stunning is the fact that Palin’s favorable ratings are now a point higher than either man at the top of the Presidential tickets this year. As of Friday morning, Obama and McCain are each viewed favorably by 57% of voters. Biden is viewed favorably by 48%.
