I'm not a fan of Chris Matthews (look through the archive of Daily Howler for reasons why I'm not) but occasionally he does something I can get behind. Like today, for instance, when he lambasted Rep. John Campbell (R-CA) for cosponsoring a bill requiring presidential candidates to prove they are US citizens (something they already have to do.) Matthews was not having any of this fellow's bullshit, and repeatedly called him out on pandering to the "wacko wing" of the Republican party. It was fantastic.
I was going to look for the video but I see that Think Progress has already linked and summarized it. Take a look.
It really is amazing that this level of insanity has such a mainstream megaphone. Sean Hannity is promoting this conspiracy. So is Lou Dobbs and Rush Limbaugh.
And while Hannity's fellow Fox News anti-intellectual Glenn Beck worries about stuff like imaginary progressive "brownshirts" having intimidated Wal-mart into developing a green line of products (rather than assuming like a sane person that Wal-mart found doing so to be profitable) an actual fascist has gone out and killed because his hatred for America's first black president was legitimized and rationalized in part by his belief in the Birther conspiracy since it gave him an excuse to believe that Obama is not a "real American."
