in California if he becomes Governor of California wants the taxpayers to give free healthcare to everyone including illegal aliens! Is it racist and xenophobic to say that’s just horseshit?
In cases where he may violate Federal Law there may be some questions. If he wants to use state funds, to provide for the residents of his state, the people of his state keep voting for him, and he follows his state's Constitution ... Well, I am going to side with the 10th Amendment (regardless how I may feel about the stupid crap he wants to do).
If he chooses to violate Federal Law in the course of his activities, I would suggest the Federal Government warn him, that they will not bail his ass out if he gets in a jam.
