Just caught this little piece of info from the electoral vote predictor 2004. It's in the narrative at the bottom of the page.
http://www.electoral-vote.com/"My $400 ad for Real Clear Politics was rejected. I guess only right-wingers can advertise there. Maybe they don't want their cosy little world interrupted by the truth. This view is enhanced by the fact that they also rejected an ad from www.politicalwire.com, an excellent (and unbiased) site for political junkies."
I'm not a reader of RealClear Politics. On another board, one of the ultra-extreme-anything-flim-flam-man-says supporters recommended it as an apolitical resource for the political forum. In fairness, because this jerk recommended it is the exact reason why I don't read it (and why I don't spend much time at the board anymore).
