Even 3 isn't terrific. History shows that Senators don't always do well in Presidential elections. The last successful one was JFK (and even that's questionable since his father practically bought him the election).

Governors...Carter/Reagan/Clinton/GW Bush...have won the Presidency in recent years. 3 out of 4 of them were elected to second terms. By having the advantage of announcing his running mate after Obama, McCain made the smart move by selecting a Governor, someone with administrative experience, who has run a State. Kay Bailey Hutchinson, while a terrific Senator, would have done absolutely nothing for the McCain ticket.

Don't agree?
We shall see... !!
