Obama was a national disgrace after he demeaned the office of the President. He'd put his feet on the Oval Office desk; he'd failed to properly salute his Marine guard; he wore a tan suit.
Trump restored dignity to the office by simulating oral sex at a campaign rally.*
*edit = To those who are sending comments pointing out other transgressions, I know I probably missed the one that offended you the most.
Talking about Trump is like talking about an anime that's been running for fifty seasons; if yopu talk about the hero fighting a dragon you have to specify which one.
