If you live in Denver, you've probably noticed that Andrew Romanoff seems to have a lock on the demographic known as "voters with yards." For months now, the only visible Democratic Senate yard signs have been Romanoff's, even in Bennet's own neighborhood. Despite my candidate preferences, I was sort of excited by the possibility that Bennet might win the primary without having any yard signs. After all, there's painfully little evidence that these things affect voters at all.
Well, it looks like Bennet's putting up yard signs after all. I suppose there's a natural experiment in there somewhere. Maybe we can see if Bennet's support goes up noticeably once the signs are installed. But given the paucity of polls, I'm not expecting a great study out of this.
