For the country, long term, I think we honestly need another Nixon like president some time soon before the executive branch gets out of control. Both bush 43 and Obama grew it so much that it's getting to the point where it's honestly a little frightening how much unilateral power it has.Trump would be such a better president than Rubio. At the very least, he'd unite Congress in realizing what kind of crazy their dealing with.
I mean we got pretty lucky with Nixon. He only destroyed Cambodia, ruined/killed a lot of innocent lives, etc. before congress found its balls again and reined executive power back a bit.
With the amount of deferred power Obama has established post-Libya someone could easily start ww3 on a bad day and claim they had constitutional authority to do it.
