Turns out there's one place GOP prez candidates spent a lot more than their Dem rivals last quarter: direct mail. Don't want to read too much into one factoid or imply that direct mail is an outmoded campaign money technology. But it was very much a key pillar of what the late 20th century GOP machine was built on. And I would imagine the political future belongs to the digital equivalents of direct mail.

I'd be curious to hear from our political and campaign operative readers about whether I'm reading too much into these numbers or whether the GOP campaign infrastructure is slower to make the switch.
