The final debate of the campaign has just finished. I didn't see it, because, like many of my suburban Monroe County neighbors, I don't subscribe to Time-Warner Cable.
Debates are only important if voters watch. Here's the list of debates in the 29th and the coverage of each:
None of these debates were broadcast in prime-time on an over-the-air station. The one over-the-air TV broadcast was during off-hours on a low-coverage UHF channel.
My conclusion: there's no reason to think that the debates were widely watched, or that they will have anything but minimal impact on this race.
