Looks like they undersampled Democrats as well, by that reasoning. But you forgot one thing: The polls sample from registered voters, not from people who actually do vote. I was asking for your evidence that significantly more than 29.7% of registered voters are enrolled as Republicans. Do you have any at all?
You are obtuse to a degree that is unmatched.

Liberal polling firms undersample Republicans and bury Democrats in an oversample in the Independent column.
Ask Scott Rasmussen, the polster who got the 2002 election and the 2004 election right, How Bush is doing.
Newsweak is biased. Their poll proves it.
