95% of people are tribal. Politically speaking the two tribes are Democrat and Republican. Most voters who register Independent do so as an affectation. 95% of people will scream bloody murder when the other tribe does something wrong while remaining silent when their own tribe does the same thing. It's actually surprising that more Republicans didn't join the filibuster simply because Obama is a Democrat. I chalk this up to most Republicans being in the Neo-con tribe, along with most Democrats.
