The Votemaster is at it again. Electoral-Vote.com tracked polls during the 2004 presidential election and is tracking Senate races this time around (he also tracks House races, but not as much). This is the best source of polling data out there. You hear on the news each day about such and such poll over the whole nation swinging this way or that. But the truth of the matter is that there are only a few Senate races out there that will affect the outcome of the election. I read it every day.
