In the aftermath of Donald Trump’s election day victory, political wonks find themselves in an urgent predicament — apparently, not a single one of them owns a calculator. This crisis is ill-timed indeed. Performing simple feats of addition and subtraction is a vital part of the wonks’ post-election number-crunching ritual. But without calculators, wonks make mistakes.

The calculator crisis has already had an impact on public opinion. Justifiably unnerved by the shortage, data-slingers have flailed in the days and weeks following the election. As a result, they’ve churned out misleading analyses full of bad math.

The worst instances of bad math have to do with the so-called “protest vote,” cast by those voters who, disgusted by the major candidates on offer, pulled the lever for marginal third-party challengers like the Green Party’s Jill Stein. To hear the wonks tell it, these voters were dupes — frauds even — and they cost Clinton the election.
