I don't think both parties are the same (although both are veering to the middle to try to attract more votes, at the cost of their bases). I just think that some in the GOP are willing to compromise Conservative beliefs in an effort to gain more votes.
I have a line drawn, it's composed of various beliefs I have. There hasn't ever been a democrat that didn't cross it. The President and his administration are standing on that line in regards to a couple of important issues (important to me).
You can call me hard-headed, but I won't move my line for somebody simply because they belong to the same party as I do. They cross it, my support goes elsewhere or stays at home. It's a variation of tough love I suppose.
No, it's more of a "do-it-my-my-way-or-I'll-screw-it-up-for-everybody" attitude typical of many so-called conservatives. You are not being unique; you are being a stereotype.
