How would you fix the Republican Party?

Ideally I would of course make it more similar to my own political views, with a strong turn to the social left, but maintenance of their fiscally right-wing policies.

What do Republicans need to do to win elections more? They're doing just fine right now. They've controlled the House nearly continuously for the past 20 years and that isn't showing any signs of stopping; they've come at least within single digits in every presidential election since 1964. They control a majority of state governments, and that looks unlikely to fall apart anytime soon either. Of course, Republicans could maybe do a better job vetting statewide candidates -- there were some disasters in 2012 that could have been avoided. But overall, they're doing just fine right now and they'll continue to do just fine for the foreseeable future. Demographic trends are moving towards Democrats, but in a two-party system when Democrats become sufficiently unpopular their new voters (or old voters; whatever) will ultimately turn towards the Republicans and hand them power. It's comforting for some to cherry-pick data to demonstrate that there has been a Democratic majority since 1992; whatever floats your boat, guys.
