I don't think Scott Brown is a discredited joke, at least not yet.
Of course, if you're a liberal, then he always was.
Having survived MSNBC on election night, they almost have an irrational hatred for him and took a lot of jabs. Maddow was muttering something about "he is the only person in America to lose to two women in Senate races!" -- I mean, what? lol
But usually, atleast in recent history, 2 losses in a row makes it a hard opportunity for a comeback.
He also defeated a woman in his first Senate campaign.
