Damn good post. But don't assume decrying Paul is somehow giving Obama a free pass. Obama's single biggest failing, IMO, is that he seems genuinely blinded by the fruit salad on a military jacket. There is no question that he has failed us on this front.
But as for Paul, I fear two very large things, amongst many others... One is that his actions will result in the deaths of many more Americans than we have killed Iraqis or Afghanis. The other is that he wouldn't really stop killing Iraqis and Afghanis anyway.
If you believe that he is so principled that he will act on all of his pronouncements then I suggest you are as naive as any Obamaphile. Case in point, Paul now says he wants to move abortion legislation to the states. But he has also stated that Roe v. Wade was damaging to the Constitution, and it is entirely obvious that moving legislation to the states is just code for banning abortion. He thus proves himself to be a dissembling politician like every other.
He also wants to allow school prayer, supports the teaching of creationism in schools, supports home schooling (read religious mental abuse of children), is for spending tax dollars to support christian schools, essentially eliminating the barrier between church and state. He fights any controls on CO2 emissions, votes against any kind of support for energy conservation or renewable energy sources, is against medical care for children (even voted against establishing the AMBER alert system), is extremely pro-gun rights, wants to abolish medicaid in favor of pro bono treatment (sure, that's going to work), is vehemently opposed to any kind of national healthcare, wants to eliminate social security, and is an Ayn Rand true believer (reason enough for me to despise him).
I'm for legalizing *all* drugs, period. I'm for getting out of *all* wars, period. I applaud Paul for his recent rebuke of the whole Sharia law nonsense. But if Paul has his way, the death toll amongst the poor and the sick is likely to surpass those in Iraq and Afghanistan. And I'm sorry, but I don't believe he'd do all the good and wonderful things you seem so ready to credit him with. It's easy to say "I will end the war"--hell, Obama said it; it seems always to be different once in office, and expecting Paul to be any different is seriously naive.
What I think you *can* count on Paul to do is eliminate the commonwealth--literally, the common wealth. Medicare, medicaid, social security... These are the bugaboos for him. It is a good Libertarian's highest calling to make sure no resources are diverted to support anyone, period. The sick, the poor, the unemployed, can all look out for themselves, as everyone *must*, and if they can't, well, then that's their lot in life. Basically, those leeches can all go die. And I have no doubt they will.
I think the "false dichotomy" here is yours--Paul to end the war, Obama to continue it. Obama deserves every bad thing you've said about him for failing to end these wars. Good luck if you think Paul is going to be any different on that front, and you'll get what you deserve if he's elected (unless you're a billionaire, in which case you'll chortle all the way to the bank).
