Well then let's look at these:
Issue 1: Rudy's ONLY "qualification" in fighting terror was that he happened to be mayor of NYC on 9/11, this doesn't exactly qualify him to do anything. Additionally, he had over seven years as mayor when he knew (or should have known) that the WTC was a target and did nothing.
Issue 2: Rudy could care less about securing the borders or dealing with illegal aliens.
Issue 3: Rudy is solidly pro-abortion.
But he looked so tough that day giving press conferences.
