She's going out of principled respect for the office of the presidency. Because she's not Trump, the guy who said that if he didn't win, he would refuse to accept the official results and declare them false, even without evidence (though he did the opposite when he won...what principle, what nobility, what logic, what an example for our kids). The guy who knowingly attacked Obama with the birther lies. She will show up and grin and bear it out of principle. Wow warbirds, way to line up behind the wrong person.
