Obama ahead of Kerry

According to Pew:

Views of Barack Obama are more favorable than were opinions of John Kerry at a comparable time in the 2004 election cycle; two-thirds of all registered voters (66%) say they have a favorable impression of Obama, compared with just 31% who have an unfavorable opinion. In early October 2004, 53% expressed a positive opinion of Kerry, while 41% expressed a negative view. McCain's image (60% favorable vs. 35% unfavorable) is similar to George Bush's at about the same point in the 2004 campaign; at that time, 57% of voters had a favorable opinion of Bush while 40% felt unfavorably toward him.
