On the day that Barack Obama announced Joe Biden as his running mate, 39% of voters said he made the right choice. A Rasmussen Reports national telephone survey found that 25% disagreed and another 35% are not sure. Women are notably less enthusiastic than men—33% of women say Biden was the right choice while 27% disagreed. Men, by a 46% to 24% margin, said that Obama made the right choice. Not surprisingly, Democrats were more supportive of Obama’s decision than anybody else—52% of those in his party agreed with his pick while 19% disagreed. However, just 43% of Democratic women said the presumptive nominee made the best pick while 23% disagreed.
