Why Eric Cantor lost his primary. I don't live in his district, I don't know anyone in his district, I don't get the same TV, newspapers, and blogs as Eric's district does. I'm not on Facebook in his district. Eric got redistricted this time around. I have no idea what that meant to his re election.
But I see lotsa pundits, with no more information than I have (which is zilch) offering opinion after opinion as to why the upset, and what it means.
"All politics is local." Tip O'Neill said once (I lived in Tip's district once upon a time). Could well be that Eric's defeat was caused by strictly local issues. Or it might not be.
I doubt that any of the TV pundits making so free with opinions, actually know anything.
