New Poll Shows Swift Boat Impact

Rasmussen Reports just posted a survey which found that 47% of America's Likely Voters have a favorable opinion of John Kerry's military service.

However, PolPundit has a different read on this:

Given that Kerry's war service has been unquestioned until recently, my guess is that undecided block are probably wavering between the favorable and unfavorable impressions. With 17% of Americans undecided, it shows the Swiftboat Veterans have had an enormous impact and may prove decisive in destroying a candidate's most important asset - his credibility.
