Thoughtomator says,"Start a new party... it's been proven time and time again that there is a huge underrepresented segment of the electorate just waiting to vote against the establishment if given a chance."
I say, "Forget it, it's also been proven time and time again that a third party just doesn't fly. Stick with the GOP, and work from within. Nothing in this life is ever going to be perfect. We have to do the best with what we've got, and we sure don't want to work for or with the Democrats."
Let's take illegal immigration as an example. It's been proven time and time again that 80+% of GOP voters want action on this issue, and there's been no lack of lobbying for that action, and the GOP has been granted a solid governing majority, yet the only proposal on the table goes directly against the will expressed by the GOP's supporters. The same thing can be said for government spending, as well, all proposals on the table increase spending.
Working within the GOP is a proven failure as a strategy on these issues. Only by giving them a real reason to fear losing voters will they become responsive to the people. There is little to no risk of most GOP voters going to the Democrats, who are even worse on these issues, so the politicians are on a practical basis free to completely ignore the will of the people.
I'd work with a pro-life democrat before I'd work with a pro-"choice" republican, any and every day of the week.
