WASHINGTON — Next on Congress’ agenda: getting rid of husbands and wives.

Rep. Lois Capps (D-Calif.) has introduced a 57-page bill updating laws on the books to expunge words like “husband” and “wife” and replace them with gender-neutral alternatives.

Among the provisions in the US Code getting an update would be the one that prohibits making threats against “the wife of a former president.” That language might need a tweak if Hillary Rodham Clinton or ­another woman is elected.

Under the bill, the word would be replaced with “spouse.”

The bill wouldn’t stop there. It would also replace phrases on the books such as “husband and wife” and instead use “married couple” as a way to bring gay marriages technically into the fold.
