When it comes to foreign policy, very close to it, yes.
This is rational. The job duties of a President are such that his statements, deicisions and actions have a far larger effect on foreign policy than on, e.g., whether/how many abortions take place.
Not all single issues are created equal. When deciding whom to make dog catcher, it makes far more sense to use the single issue of "how good would he be at catching dogs?" than it would to use the single issue of "what's his position on abortion?".
So please, tell me Rudy's foreign policy experience. Explain to me why he pushed a corrupt crony for the most important anti-terror job in the country. Ask why he fought federal court rulings against NYC's sanctuary city policy. And why he took guns away from law-abiding NYC permit holders.
That is NOT the mark of a man that is serious about national security. Just promoting himself.
