(CNN) -- Conventional wisdom can be a dangerous thing. The media and political chattering class are rushing to explain how Republican House Majority Leader Eric Cantor could lose his primary election to a relatively unknown challenger. No one saw it coming. And apparently it's not enough to just bask in the shock. We need answers. But this loss is not just about immigration reform or even the tea party. It's about the insanely unpopular Republican leadership in Congress and one of its figureheads, who increasingly made little legislative progress for America or for his district. Yes, in the waning hours of the campaign, immigration was a key issue. But a poll taken on election night shows that fully 72% of Cantor's very Republican district support immigration reform including a path to citizenship.

What suffered in this race is the shell of our political system, now grinding to a halt, Kohn says

Cantor wasn't conservative enough for base but too extreme for everyone else, Kohn says
Arguably, the reasons for Cantor's demise are more subtle -- and ultimately hold even more danger for the @placeholder and the nation.
We need (at least two) political parties in the @placeholder that wrestle over the big challenges and needs of Americans and, yes, at times actually pass legislation and get things done.
