On the anniversary of Senator McCain’s death, the Libertarian Party of New Hampshire last week tweeted a photograph of Meghan McCain crying over her father’s coffin, with the tagline: “Happy Holidays.” The tweet got 11,500 likes and thousands of quote tweets and replies, many of them critical.

Ms. McCain retweeted it six times with commentary, calling it “hideous — even by twitter standards.” Her retweeting gave the Libertarian Party of New Hampshire a larger platform than it usually enjoys and national attention.
