This attitude is exactly why the GOP is trending left -- they think all right-wingers are as mindless as you, so they have no incentive not to move left in order to get more votes. You enable GOP liberalism, just like many black voters keep rewarding Democrats who have nothing but contempt for their values.
The primaries are where you try to make your point. Being involved at a grassrotts level is where you make a difference. Handing the dems the Presidency for four years...you want to think of that as noble, you go right ahead. You stick to your guns.
Maybe future President Hillary Clinton will send you a thank-you card. Mindless, indeed.
