And Hillary didn't even complain about nonsensical "voter fraud rigged election" for the next 2 years. She just conceded gracefully on election night.
Maybe you forgot, but Hillary started to complain a bit later:
Hillary Clinton Labels Trump an ‘Illegitimate President’
https://news.yahoo.com/hillary-clinton-labels-trump-illegitimate-170547434.htmlHillary Clinton said that Donald Trump is an “illegitimate president” during a Wednesday appearance on ABC’s “The View.”
Jimmy Carter was more specific about what "illegitimate" means:
https://www.theguardian.com/us-news/2019/jun/28/jimmy-carter-trump-illegitimate-president-russiaAt a conference for his human rights organization the Carter Center, the former president said a full investigation “would show that Trump didn’t actually win the election in 2016”.
“He lost the election and he was put into office because the Russians interfered on his behalf,” Carter added.
The event moderator, Jon Meacham, asked if that meant Carter thought that Trump was an illegitimate president. Carter then briefly paused and replied: “Based on what I just said, which I can’t retract,” Carter said.
