We all can make up our minds about things based on generalizations rather than details.
But you know what they say about details and the Devil.
If you think having a John Murtha-type as SECDEF is the same for the country as having a John McCain-type, I guess you are too smart to subject your thinking to simple analytical tools.
Frankly, I don’t want either of the Johns to be SECDEF.
I don’t need any analytical tools to tell me that I shouldn’t ever vote for a cross-dressing, gun grabbing, baby killing, illegal alien coddling liberal for any office, let alone POTUS.
