A company called Wilson Research Strategies does all sorts of polls to gauge the American public. Recently (May 5-8), they conducted one that asked 1000 registered voters, "Who is your favorite super-hero?" This poll has a margin of error of ±3.2% and I offer it here for whatever it's worth, with the suspicion that Spider-Man's stock has probably risen since the movie came out.
- Superman – 27%
- Spider-Man – 15%
- Batman – 14%
- Wonder Woman – 11%
- The Incredible Hulk – 7%
- Flash Gordon – 4%
- The Bionic Man – 4%
- Other/Don't Know – 20%
