Maybe the Republican Party needs to admit to their errors, reestablish/reaffirm their core principles, and regain conservative support. Otherwise, it is and will by their fault that we have a new majority of left wing liberal traitors.
I did my part in Republican Party politics over the past 10 years. As a conservative I found that I was fighting a losing battle within the party. The knife wounds in my back from party leadership are still fresh. The foxes run the henhouse. The liberal elitists run the party. Fix that and we have a chance of reuniting the party and winning the majority back. Until then, the divide will only grow wider. You can bandage all you want but until you stop they guys with the knives you'll never stop the bleeding.
