It's one thing with it just a few polls and it is within 10 points. But this is way too much to explain by bias pollsters.
Anyway, Rassmussen is one of the most reliable pollsters. And it is run by Republicans.
I've been turned off by the wholesale Freepdom denial of polls. Any one poll is suspect. Look at a dozen polls for some consistent message and more often than not, you get a meaningful measure of the political landscape.
Many Freepers are too young to recall the Clinton Impeachment. Poll after poll showed very low support for removing Clinton from office. Freepdom insisted all the polls were wrong. Of course, it was the Freepers who were wrong.
Clarity is often scarce on FR, I admit.
