Is Demanding Justice One Day and Supporting Trump the Next Good Politics?

Americans have reason to be cynical about the honesty of their politicians, so it shouldn’t come as a surprise when an apparently sincere Republican U.S. representative (in this case, Mike Gallagher) switches from being a supporter of justice to a Trump lackey overnight.

I would think, however, that it would be a poor decision from a practical perspective.  Doesn’t it make you look like a lying ass**** to voters in both political parties simultaneously?
