I suggest anyone considering voting for Ron Paul make sure they first understand the nature of libertarianism and it's implications. Paul once ran for President on the Libertarian Party ticket and still considers himself a "small l" libertarian. This is a movement that opposes things like publicly funded construction of roads, the US postal service, anti-trust laws, labor protection laws (All of them), environmental protection laws (all of them), the income tax (Which they equate to slavery), a legal minimum age of consent for sexual acts, government recognition of marriages, social security, Medicare, Medicaid, the Civil Rights Act of 1964, and a whole laundry list of important laws and programs, while favoring legalized prostitution. Ultimately they want a government so minimal that the end result would be either anarchy or a small group of large corporations and associations that essentially treat the rest of us as slaves.
I'm not saying Congressman Paul is in line with the libertarian position on all of these items (He probably has to be more moderate than that to have been elected to congress), but people should be aware that he has freely aligned himself with a party devoted to many of them in the past and still uses the term "libertarian" to describe himself. I could never and would never vote for a libertarian under any circumstances, personally.
I do agree with Bill on being against the war and being pro-life, and it's nice that the Congressman agrees with us on those two things also, but overall the Congressman becoming President would be a huge disaster for this nation, in my opinion.
