It certainly looks like a job. Of course Trump won't be indicted. He's too big to indict in America. He could, as he states, shoot someone and not only get away with it probably get a boost in the polls. That's just life. And the truth is is that this is a law we know all politicians break and nobody actually gives a shit. It's frankly a stupid law that shouldn't exist but it does. And he broke it.
There are a litany of reasons why Trump should never be president and frankly this (while accurate) is a desperate thing to cling to.
If Carson had said Trump promised him Secretary of Education in return for his endorsement, that would be illegal. Carson said nothing of the sort.
And yes, it's desperation time, apparently.
