Chait spots one:
Donald Trump's implosion still leaves a huge opportunity on the Republican right. Trump was a horribly, horribly flawed messenger — his past was filled with support for Democratic politicians, causes like single-payer health insurance, and he horrified Republicans in his high profile first speech in Las Vegas by dropping a series of f-bombs. But Trump's message itself was deeply powerful. There remains a powerful demand for a candidate to fill it.
Palin! After Trump, whom she has showered with praise, she seems conventional.
