So McCain is billing himself as "the original maverick". Uhh ... no. A "maverick" is supposed to be independent. When has McCain ever voted against Georgie? On anything? I don't remember any. He has mildly criticized a couple of things that Georgie did, but when the time to vote came, he was right there. When he was there at all -- McCain has the worst attendance record in the Senate.
Besides, those of us Of A Certain Age know the real "original Maverick" -- as played by James Garner.
Does McCain really want to identify himself with a professional gambler with no fixed address and dubious morals? The pic shows Bret Maverick gambling, with a gun and money on the table. Maybe this really is the "maverick" that McCain thinks we want. Unfortunately, McCain lacks Bret Maverick's intelligence, charm, morals, and sense of humor.
The most important thing, of course, is that Bret Maverick is a fictional character. He always won (or at least survived) because the writers wrote the script that way. Those of us in what is laughingly called "the real world" don't have that advantage.
