If the Republicans want to take back the White House anytime soon, they need to develop a moderate DLC-style wing in their party that breaks with traditional GOP thinking on some issues while still remaining identifiably right-of-center. I think it was Al Gore who said something like "the ideas of the 30's won't solve the problems of the 90's." There needs to be someone in the GOP who will say that the ideas of the 80's won't solve the problems of the 10's and beyond. Reagan nostalgia will only get you so far when your identity to most people under 35 or so is the party of George W. Bush, Donald Trump, and Ted Cruz.
Yeah but the problem is Republicans think the demography of the country is currently in 1985. That's the problem. Just listen to Conservative Talk Radio they think the country demographically is the same one that they graduated High School in the 1970s or 1980's. I graduated HS in 1998 and the Hispanic Population has grown from 12% then to 19% currently. That's a sizeable change in an 18 year span.
