McCain likes to shoot from the hip. Shoot first and ask questions later. Exactly the same as the current occupant of the White House and look what that has gotten us.
I also find it interesting that former career military leaders have been less than stellar presidents. Except for Washington, every former military leader, who became president, are among the worst of the presidents. Grant had a corrupt administration, Jackson was responsible for the "Trail of Tears" and defiance of the Supreme Court, and Eisenhower did very little except to give us the Interstate Highway system and, to his credit, warned us about the military-industrial complex. Unfortunately his warning was never heeded.
McCain has shown himself to be less than honorable with his involvement in the Keating savings and loan scandal.
Finally, I have to ask: Does any one, in their right mind, really want Sarah Palin just a heartbeat away from the presidency?
