If nothing else, in a few weeks we will have another round of data for whose polls matter most and whose are accurate, if any.
A lot of freepers have very dogmatic and condescending opinions about polls ("polls are useless" or "polls tell the whole story"). If these polls hold up and GOP loses, then, we will know that they aren't crap. If the GOP escapes narrowly, we will know they are good within the margin of error. If the GOP wins handily, then we will know that they are in fact crap.
I anticipate that the GOP will narrowly hang on to the Senate, b/c I think Allen wins. But I think we are going to end up with a mere 51 (but, no Chaffee to worry about).
In short, I think the polls are within the margin of error...but who the hell knows at this stage?
