@revelette1,
That would have been Warren Harding, who ran a populist campaign, breezed into the White House, and immediately began dismantling what few regulatory agencies there were in 1921, as well as handing big tax cuts to corporations and wealthy individuals. He died in office, and after his death, the depth and scope of corruption in his administration came out. His former popularity plummeted, and his wife became a pariah. (Some supporters tried to blame her for the corruption and scandals, but I have since decided that Harding owns that himself.)
However, Harding did play a good game, and appeared to be a sincere and dignified. In an era in which investigative journalism hardly existed, he got away with the dog and pony show while he still lived.
