The Harris poll has Bush winning by 4 through its telephone survey and Kerry winning by 2 through an online survey. They find that those without landlines are going strongly for Kerry and posit that indicates that telephone polls will underpoll for Kerry. Wouldn't an online survey also miss a substantial chunk of the population? I don't know which candidate is more the candidate of computer-users, but I'm very suspicious of such interactive polls such as Zogby uses.

They also say tha 24% or respondents have already voted (does that mean that lines will be short when I go tomorrow?) and that Bush is winning that group by 6 points.
