That thread, which I've been following, has been around for days, and yet only today the voting pattern changed in a very lop-sided way.

Going from a c. 3-10% difference over many days and then having a 75+% difference in the opposite direction for votes within the past 24 hours, on a rather large number of votes cast today? That thread explains some increased traffic, but the very dramatic voting shift? Maybe weekend voters are different than holiday voters, and this is the post-holiday hangover effect?

Boss Tweed and Tammany Hall hand out a bunch of Christmas hams and turkeys on Boxing Day, as a reward for support? But that was yesterday.
