I consider your post to be a profound rationalization.
There are two candisdates, a Republican and a Democrat. Because you have objections to McCain, you erect barriers and develop mental barriers against voting.
You are apparently self justified by the rationalization to an Obama Presidency because by not voting for the Republican, you are allowing the Democrat to win.
Are your more loyal to the cause of conservatism, and therefore to our nation, or are you more loyal to the GOP?
I am not rationalizing anything. I am considering what is in the best interest of the USA and our freedoms that go with it. I care not the least for the short term interest of any group of politicians (political parties).
