Zogby is a famous lefty poll. No doubt they're hoping Republicans will fall for this gambit and push creationism, a guaranteed road to political defeat.
Remember the re-election rate of the Dover school board.
Or, this poll only says people believe all evidence should be taught.
Which I think most evos would say, "yes" to.
Since ID has no evidence, this poll does *not* say these folks support ID.
You can relax. I doubt it will become a big political issue. Maybe on the local level, though.
