One gets an engagement ring; the other goes home, ugly-crying in the back seat of a limousine, knowingbr that maybe she won’t be alone forever — the network could tap her to star in the spinoff, “The Bachelorette.”br I know what you’re thinking: “The Bachelor” wasn’t even the reality show that our president was on!br He also understood that social media had flattened the once crucial distinctions between “politician”br and “entertainer,” and turned viewing into a participatory sport, where it almost didn’t matter what viewers were snarking about, whether it was a politician or a pop star, a political convention or an episode of “After the Final Rose.”br For months, my fellow reality TV fans and I watchedbr and tweeted, appalled and enthralled, as Mr. Trump went after Mexicans and Muslims, war heroes and Gold Star families; bashing beauty queens and retweeting anti-Semitic memes while still staying in the hunt.br I watched — and live-tweeted — “The Bachelor.”br For those who don’t know the show, which will end its 21st season on Monday, the premise is simple:br A single man is presented with a smorgasbord of women to date for the following several weeks.br “Are you not entertained?” Alec Baldwin, in character as the president, growled at the camera on “Saturday Night Live.” While I’d usebr a different word — one like “terrified” — the Trump presidency is, indeed, must-see TV, with one crazy plot twist after the next.br While “The Bachelor” made trash-talking part of the game, even the jerkiest bachelor had nothing on Mr. Trump, who assigned his fellow candidates demeaningbr and somehow perfect nicknames, tweeted unflattering memes about a competitor’s wife, said unflattering things about another’s looks and mocked a third by flailing around onstage with a water bottle.
