Alan Simpson, a longtime Republican senator from Wyoming who championed bipartisan solutions and steadfastly advocated for a moderate blend of conservatism, has died. He was 93.

Pushing the 1986 immigration reform bill through Congress — his major legislative accomplishment — was like “giving dry birth to a porcupine,” he quipped.

A plain-spoken lawmaker from Wyoming, he balanced his conservative views with moderate stands on abortion rights, gay marriage and immigration reform.
