My apologies. I should have been more clear - thanks for pointing that out.
Ron Paul has received the most campaign cash from military personnel among Republican candidates.
Is it convincing? I don't know what that question means. But either way, the numbers speak for themselves. Those who donate to politicians seem to favor those opposed to extending the war in Iraq. (Not that Obama will actually end it, or not escalate the war into Iran, but that is how he presents himself to the general public.)
I'm just saying that there does seem to be some amount of support for Ron Paul's foreign policy ideas. To what degree I have no idea, as the military people I know are relatively apolitical or tight-lipped about their ideas.
