It was never a whine. Any objective observer who really analyzes the differences in coverage would have no choice but to conclude a general bias against Paul in the media. Honestly, for a while in 2007 I didn't really believe it either, but then I began seeing every single media organization leaving Paul's name out of a poll even when he was ranked higher than other candidates they did mention. Despite massive fundraising successes he got only a flurry of coverage in the first day or so and then nothing. I saw them touting Huckabee as a "dark horse" well before he had any major showing in the polls. Then came some of the blatant actions by Fox News that rose to such levels of absurdity that they were even omitting his image and reporting as though McCain had come in second in Nevada even as the result going by at the bottom of the screen clearly showed otherwise.
Being upset about that is not whining. This time around a lot more attention has been given on this issue because it has become increasingly obvious. Several third-party studies have demonstrated that he had been the least-mentioned candidate even when he was polling in double digits. Only now that he has risen around 20% have the media shifted tactics. Have you not been paying attention to what people like me have been saying? None of us Paul supporters are surprised that there has been more coverage. It is necessary that the media maintain the appearance of credibility, especially after people like Jon Stewart pointed it out to millions of viewers, so there is no choice but to give him some more coverage.
Just as was predicted, now that they can no longer play the "he will never win a single state" game the media have shifted gears, though I imagine they will always make some effort to downplay or omit Paul in their coverage. It is now, as predicted, more about attacking the legitimacy of the Iowa caucuses as an indicator of who will win the nomination (while a first place finish has never been treated as a lock, it has regularly been treated as important) and smearing Ron Paul. Since he also has a very strong showing in New Hampshire right now a win in Iowa could easily catapult him to a win there given the short time frame. The next tactic would simply be to write off New Hampshire because it is a small state, with the Republican Party establishment insisting on the need to offset the influence of these smaller contests, and the pundits will say that South Carolina is the real test.
