I will take exception to this remark.
Your entire exception speech doesn't hold up IMHO. A classic case of mind made up long before the cards are on the table and the all in call is made. You and those like you on the "principled" side of the issue, sit in judgment based on the past present and future, long before the present and future are known.
Placing Rudy, and Mitt in a position equal or worse than the potential dem candidate whoever that might be. Worse, you leave yourself no room for change. Not a good or wise position for yourself, your fellow men, or the country you profess to love, that provides to this point the freedom for you to worship God after the dictates of your conscience.
If you don't make principled judgments, then what sort of criteria do you prefer?
