Good thing the US isn't supposed to be a democracy anyway.
Getting back to the actual topic, I might be inclined to agree in the matter of Congressional office, but I don't know if I can agree with the article's core premise of
>The troubling trend of debate-skipping is not limited to one party, one region, or one type of officeholder. It is evident in both close-fought campaigns and blowouts alike.
The author also doesn't give enough attention the element of a lot of solid color states when it comes to multiple candidates in the same party debating each other, not just a two-person affair. Something else of note is that a lot of the hoi polloi don't realize or care that the majority of official party positions or opinions on the Administration are irrelevant to any given office, especially at the state and county levels (excluding the legislative district reps/senators), hence Yepsen's quote at the end being fairly accurate.
It should also be noted that focusing on the efficiency of watching debates when it comes to gaining voters is pretty low compared to other avenues, especially when the main priority is voter turnout in the first place.
