nice democrat article or study? This is true, however it goes both ways. Many follow democrat leaders blindly. Republicans in congress don't just follow the party, while democrats stick together and vote their party line (with the exception of WV). There seems to be several republican elected that might actually be democrats in disguise, such as Flake and Romney for example.
With that said, many people fall into that a bit of knowledge but not the whole story. The difference being the thinking process (common sense). Democrat media still hasn't figured out how their polls were wrong, or they don't care and continue to push their agenda.
