The more I learn about Justin Amash, the more I think he might be the only candidate that a qualified (i.e. serious) Democrat could actually beat.
Amash is a Libertarian at heart, and it appears that he has drunk the Tea Bagger's cool-aid and is fully on-board with the right-wing fringe of the GOP. On one hand, I think this makes him a strong contender in the GOP primary, where I suspect the baggers will have an outsized influence.
In the general, the key will be to force him to admit, over and over, that he really does think Social Security should be abolished and Medicare should be turned into a means-tested insurance voucher program. Unlike a seasoned politician, Amash may actually get up and say what he believes, instead of burying it in a bunch of poll-tested bullshit.
It will be up to the Democrat to force Amash to throw his support behind Paul Ryan's roadmap to the GOP future and not let him get away from it. Only when voters are viscerally confronted with the insanity of the GOP's platform will they understand how radical it really is.
On the other hand, maybe this is what the majority of Kent County actually wants, in which case Canada is really not that far away.
