Gallup Inconsistencies

Donkey Rising has a great post about the ridiculous Gallup poll methodology, The "How Can Gallup........" Game

Like, for example:

How can Gallup......have Bush up by 13 nationwide, when he's only up by 2 points among Florida RVs?--and according to their own poll!

How can Gallup.....have Bush up by 13 nationwide, when he's only up by 2 points among Nevada RVs?--again, according to their own poll.

How can Gallup....have Bush up by 13 nationwide, when he's only up by 3 points in Ohio, according to Fox News?

How can Gallup....have Bush up by 13 nationwide, when he trailing by 5 points in Pennsylvania and 2 points in Michigan, according to Fox News?
