Principled Objection

We've been fighting against an imperial presidency for five and a half years.  Every time we go to the floor and push back against an overreaching president, we get accused of being partisan at best and racist at worst.  When we do it against a Republican president, maybe people will see that it was a principled objection in the first place.  So we actually welcome that opportunity.  It might actually be fun, being a strict-constitutionalist congressman doing battle with a non-strict-constitutionalist Republican president.
