Why Justin Amash is particularly vulnerable to a primary challenge

Michigan Republican Rep. Justin Amash made news this weekend when he declared that President Donald Trump has “engaged in impeachable conduct.”

That a Republican member of Congress said this should not be taken as a sign of any sort of revolt or even mini-revolt by Republicans against Trump.

Amash is an unusual congressman who isn’t representative of most Republicans, and it wouldn’t be surprising if a primary challenger, such as the already declared State Rep. Jim Lower, defeated him next year. CONT.
