Back in March, I made a long-odds bet that Michelle Obama would be the Democratic party’s vice-presidential nominee. I knew that in her memoir, Becoming, she had said that she wasn’t interested in high office. But political candidates always claim they aren’t running — until suddenly they are.

Joe Biden, the presumptive Democratic nominee, had already said he’d take Michelle as his VP ‘in a heartbeat’, which struck me as funny since, if Biden’s heart stopped beating, his VP would become commander-in-chief.
