John McCain has reached new heights in conservative Wonkosphere buzz, clocking in at 58% yesterday, compared to Romney’s 28%. The race, as far as conservative bloggers are concerned, is down to McCain v. Romney, as they cornered 86% of all their attention. Ditto is happening on the liberal side, with Clinton and Obama accounting for 85% of liberal buzz and 60% of total buzz after Obama’s overwhelming win in South Carolina. McCain’s 58% is the highest one-day conservative buzz share we have seen this campaign season, beating Ron Paul’s 50% level which he hit in November. Buzz share is a zero-sum game, so if McCain is surging it must mean others are hurting, and indeed they are. Mike Huckabee’s drop is the most shocking, as he’s gone from a respectable 20% ten days ago to 3%. Three percent! Huckabee’s rode the blogosphere buzz train into the MSM spotlight, so this decline is likely a death march into Ignoredom. Rudy Giuliani, who had spent five days above 10%, fell to 6%, and Ron Paul has been under 10% for the last three weeks. The conservative blogosphere is now McCain’s to lose.
