We can all agree that the GOP, as they stood Tuesday night, is just about done. The midterms may see some twitching from it, but that'll be the last time the Republican Party as we see it now will be taken seriously by enough people to stand. If they wish to continue to attract either social or fiscal conservatives there's a few things that I can see they'll need to do.
As Meshakhad pointed out, you gotta do something to, well, if not attract Hispanics, you certainly want to stop scaring them. Pretty simple to say, right? Just stop treating everyone brown as if they just crossed the border last week with 15 kilos strapped to their backs. You want to go after illegal immigrants with a hard on? Knock yourselves out. Just get better at differentiating between legal and illegal immigrants.
Second, you gotta have a system for dealing with those Todd Akin type verbal oopsies. Sometimes circling the wagons isn't the best answer. For something like that, cut him loose. Very publicly withdraw his funding and run the everloving hell out of someone else. Have your high profile people come out and say that shit isn't OK and it's not going to be put up with. Yeah, it sucks for you to do that. But how many Senate seats did you loose because of that? How much did Sarah Palin's inability to answer a question without a script hurt?
Third, you gotta distance yourself from the extremes in media. Sometimes you have to remind people Rush, Coulter, Hannity, Levin, Beck, and other Fox talking heads doesn't speak for the Republican Party. News flash, Fox (and republicans, you pay attention too). The majority of people know you're lying. A majority of people see through the fear mongering. Now, what with the First Amendment and all, I understand you really can't shut them up, as much as everyone reading this would enjoy the quiet. But you can do enough other things, like strongly suggest candidates stop going on the shows or coming out against them. A statement that says hate is not a conservative value (I know, I know) might go far enough for it to be worth a second look.
Fourth, it appears the GOP is under complete control of their special interests, namely big business, big Pentagon contractors, and the religious right. I'm going to talk about them backwards. The country is becoming more secular by the hour. You had two states legalize marijuana (at least one of them for recreational use) and a couple for same sex marriage. And by popular vote. While that's sinking in, let me put this forward. Women don't want the government to pay for abortions or birth control. They do, however, want birth control and abortions to be there when they need them. The Pentagon has always been a monkey on your back. I'm really not sure how to get around that problem, but it is a problem that needs to be addressed. And big business, well, I understand you gotta dance with the guys who brung ya. But you're going too far. It's OK to be pro big business. It's not OK for us to see their mouths moving as you talk. Pretend like you believe it's the right thing as opposed to appeasing the money. I remember the DNC dealing with that same issue in the late 70s-mid 80's. It's how you got two terms of Reagen and Bush Sr. for an impressive 12 year run. Guess what you're seeing right now. Give up? The shoe on the other foot.
Last, get your extreme element under control. I would have thought that'd be a gimme, but it looks like it's not. You can't say your party's primary goal is to make Obama a one term president. Yeah, Obama should have done a better job with Pelosi, but that's not an excuse. If the Tea Party is going to be a part of the republicans, then somebody needs to get them in a room and explain how to act on camera and with press releases. If they aren't, cut them the hell off. Seriously, if you want to be a real party, figure out how to marginalize your extremes. They're making you look like a joke.
That's about all I have for now. These are the biggest problems I could see. There are others, but they need to figure out how to address this stuff in a hurry if they want to field a real candidate in 2016.
