You make a good point here. I agree that Democrats have really been overtaken by militiant ideology on certain issues. Bullying from their lobbying groups. The media narrative is this is the new great enlightened America (politically correct), but polls of the people often do not confirm that narrative. Thus the phenomenon of Trump, a grassroots backlash.
I do fear though that Trump will divide the GOP; he is not the right person to “make America great again.” In this sense, he could well shatter the GOP and its chances to win in November. Republicans are increasingly divided and open on economic and social policy. Ideas that would have never been accepted by the party, Trump gets away with all the time - anti-trade, national health care, Planned Parenthood.
The GOP is much more conflicted and fluent on policy than the Democrats - right now that is creating vulnerability and disorientation. But sooner rather than later, I think the GOP will emerge as the party of the people, the center, the next big thing if you will. I have a hard time seeing us get it together that brilliantly by the fall, but it is coming. There will be a resifting of what the GOP stands for, for better or worse, mostly better I think.
The question is when and who will be the leader who emerges to lead the next wave of conservatism. I say maybe Rubio, 2010. There is a pretty slight chance we get it together in the fall I guess, Cruz/Rubio. The key to doing that is frankly what Trump does with his very limited skills and fanatic troops at the convention. Does he play ball with the party. And he could also win 1237 outright - I think we lose the general there - that would really be a tragedy for the party and the country. The wrong person has momentum…for the right reasons.
