Nope.
There is no legal doubt that under the laws of citizenship, McCain is eligible.
Until all BC of Romney and his father are shown,
the evidence is that he is NOT eligible.
(just like Obama whom he helps and protects)
You can't say that with legal certainty. Most who claim this ardently want to believe he is natural born because they themselves were born abroad to parents in the military, or their children were. Several attempts at altering the very Constitutional eligibility requirement at question have been made in the form of Bills over the past decades, for the very reason of making children born abroad of military parents eligible for the Presidency. Such an undertaking would have been totally unnecessary if what you claim to be true, actually were true.
I've seen very persuasive arguments that McCain was not in fact eligible, from Gabriel Chin and Lawrence Solum, two very credible authorities upon Constitutional law. I won't go so far as to say point blank that McCain was not and is not eligible, but there clearly are questions. The Panama Canal Zone was leased and was not US sovereign territory. There is some question as to whether McCain was born in the Zone or not, even so. McCain's very citizenship was at question up until the 1952 McCarran-Walter Act, according again to some credible authorities.
It's far from cut and dried, no matter how badly you want it to be.
