The GOP finds itself trapped in a marriage that has not only gone bad but is coming apart in full public view.

After five decades of shrewd strategy, the Republican coalition Richard Nixon put together in 1968—welcoming the segregationist white South into the Party of Lincoln—is now devouring itself in ugly, spiteful recriminations.
Democrats have a great opportunity to force the question on the nation in 2016. Instead of playing limp and vague, Dems can launch what Howard Dean called for in 2004: a 50-state strategy that runs on liberating issues. Instead of ignoring GOP bigotry, the Democratic ticket can promise to challenge it on every front and attack reactionary Republicans who try to impose the past on voters.
Above all, Democrats should demand that Tea Party rebels explain why they are in league with a party that intends to cut Medicare, Medicaid, and Social Security in order to finance more tax cuts for billionaires. As Scott Lilly suggested, if common folks ever understand the corrupt nature of the Republican coalition, we will see a popular rebellion that makes the present chaos look like, well, a tea party.
