well, a constitutional republic gives you the most freedom you can possibly have, but with a rule of law, enumerating the feds powers and giving the rest to the states, with checks and balances and separation of powers.

currently, we are pretty close to dictatorship, but that's not a reflection of constitutional republics, our CR has been subverted. we don't operate how the country was intended, and haven't for well over 100 years. if we did, we'd be closer to anarchy than to dictatorship, in my opinion.
