Republicans: During the Presidential run of 2016 what do you think about defecting your party?

From what I understand the Republican party is about 50% Evangelical, and hard right on many issues. Then there is this other part of the party who is rather moderate, especially on social issues. From where I sit, and my glasses are fairly blue I must admit, we will call them indigo, coming close to the purple middle, it seems to me there are way more chances of getting a moderate Democrat than a moderate Republican through the primaries.

So, if you are a Republican who wants fiscal responsibility and is liberal on social issues, do you think your vote could cause a bigger shift among the Dems than the Republicans?

I keep waiting for the Republicans to wake up and tell the extreme right wong of the party to take a flying leap, but it isn’t going to happen I don’t think.

The question can go to Democrats also who might think going to the Republican party and overpowering the far extreme right might work.

I realize the question is very biased, but feel free to flip it on its head or argue the basic premise.

Thanks.
