Maggie Haberman, a sharp observer of Trump for the NYT, lays out on Twitter the challenges he'll face as president.
- Trump has never had a job with the same demands as the presidency
- Congressional Republicans still don't have clarity on where he stands on the issues
- It's unclear who he'll rely on outside his family and how he'll handle being away from his sons
- How will his style and "theatrical, constant-contact approach" translate to the White House
