I doubt that Romney has any real deep convictions about our military as neither he or his four sons who all were certainly eligible for military service at some time never served. That being said I will say that would not in itself stop me from voting for Romney. However, what will not allow me to vote for Romney is if his choice for VP is someone who is not eligible for POTUSA by requirement of the Constitution as NBC. For me Rubio does not qualify for this reason and now his latest subscription for international involvements.
I don't know about the NBC stuff, but I suspect that if true, the Dems/Marxists are well prepared to run with such an issue.
