... You are entitled to your opinion. So am I is a brazen cop-out.
Why are we both in the Republican party? I can tell you why I've voted straight Republican for more than three decades -- in general, because I figure Republicans will act to reduce the size and scope of government.
Why are you in the Republican party? If you are in the Republican party because you trust them to do a better job with the same growth in government, then one of us is in the wrong party.
If you are like me and you essentially count on the Republican party to be a force for reducing the scope of government, then it is not opinion, but straight FACT that you -- we -- have been voting for candidates who act to grow government. That's a fact -- you may be entitled to your opinion, but facts is facts.
The “fact” is that until and unless someone who can get votes across party lines runs, this whole discussion is hypothetical. No one currently publically considering running can do that. Nor, does anyone come to mind.
