These isolationists who think the US should "mind its own business" also think the US should cancel all foreign aid. Not just the ESF and military aid you oppose, but aid for women's education, family planning, microcredit programs, UN support, refugees, and whatever other (few) programs funded by the US which actually help the poorest of the poor. As for the Iraq vote, I'll take an elected representative who's wrong but sincerely believes over one who votes however the wind is blowing. The first can (sometimes) be educated, and at least can be debated and refuted on open terms. The latter just votes however they feel with no consistent argument or philosophy.
