Every Democratic nominee who has ever lost a presidential election has followed the process. Hillary conceded the morning after e-day, after a late night count, saying "We owe him an open mind and the chance to lead" (turned out: not so much). Kerry conceded the morning after e-day (according to Bush's staff, the concession was "gracious"). Gore contested the results to the extent allowed by the law. Bush had the better argument, and prevailed in court, after which Gore "accepted the finality of the outcome". Dukakis conceded during election night.
Really, there's just not much partisan to say about this, other than that Trump, who happens to be a Republican, has the distinction of being the only President in the history of the United States not to honor the process.
