This evidence provides tangetial empirical validation for an article I wrote last year about how the the Republicans have become a more intensely ideological party than the Democrats.
* "We then computed a cosine similarity measure between all pairs of blogs, this time using a TF ¤ IDF metric, where the entry in xA corresponding to phrase p is given by fA,p ¤ log(N/np), where fA,p is the number of times the phrase p occurs in blog A, N = 1, 768, 887 is the number of blogs harvested by Blog-Pulse between Oct.-Nov. 2004 and np is the number of blogs mentioning phrase p in all of the BlogPulse dataset. We modified the cosine similarity metric to take into account only mentions of the same phrase by two blogs made within a day of one another. Overall the differences were too slight to be significant."
