Who's thin-skinned

As we go into the final two months before the Iowa caucuses, the question remains about Donald Trump.
Is he too thin-skinned to be president?
Or are there too many people too thin-skinned to handle Trump being president?
Everything he does offends people.
He says he doesn't mean the offense taken, but every week there's another offense out there.
And yet he remains atop the polls.
That's probably what offends the thin-skinned most of all.
