ELI5: why hasn't the US seen more recent unmarried presidential candidates?

A good prospective first lady can be a huge asset in a campaign. They can attend rallies and fundraisers while their husband is elsewhere on the campaign trail. They can stress a different set of talking points, and thereby appeal to a different demographic of voters.

So an eloquent, politically active wife is kind of a force multiplier in a campaign. Bachelor/widower/divorced candidates are essentially playing at a disadvantage.
