Twitter offers a delightfully easy way for anyone to indulge in some schadenfreude. If someone makes an observation or prediction that’s ultimately proven to be embarrassingly wrong, that unfortunate tweeter may well discover that his adversaries have long memories. Call it the belated retweet.

Liberals relished it after the 2012 election, pulling up months-old tweets from conservatives who mocked polls and confidently predicted doom for President Obama.

But White House spokesman Jesse Lee might have set a new bar for the practice on Thursday, after the Obama administration announced that six million Americans have signed up for health insurance through the Affordable Care Act.

A particular focus of Lee’s taunts was a popular meme on the right during the health care law’s disastrous rollout. Ted Cruz and others wryly observed back in the doldrums of October and November that the number of Obamacare enrollees couldn’t even fill various athletic stadiums.

Lee then twisted the knife a bit more and turned the gag back on conservatives:
