Priebus harnessed recalcitrant Republicans to support Trump, dedicated a lot of RNC resources to his election, and is an effective manager (though not as effective as Kellyanne Conway, IMO.)
And he’s a friend of Ryan’s, so he might be able to help with Congressional relations. (But they already have Pence for that.)
Unfortunately, as Chief of Staff, he’ll probably bring in a lot of Establishemnt Republicans who don’t share — or even see — Trump’s vision, and as Morton Blackwell reminds us, “personnel is policy.”
Trump has good instincts.
I will trust his judgement more than yours with all due respect.
And for heavens sake, he is an advisor, not a cabinet choice, if this report is true.
