Trump will have more latitude in the new Senate

True, but Mitt will be a blocker now.

True, but Mitt will be a blocker now.

If so, he is inherently high profile enough for Trump to be able to humiliate him at will. As a first year guy, his ability to manipulate behind the scenes will be limited, as McConnell et al won't want him horning in on the power ahead of time. McConnell and Graham seem to have figured out that this is Trump's party now. That means you trust neither, but you can still work with them.
