Not all encompassing at all though... I'm fiscally conservative, but want a strong military, but I'm agnostic.
Show me a party that believes in the first two and doesn't shove god in my face. Please.
Some of you might be fiscally liberal, want a lot of regulation, but doesn't want family values trampelled on. There isn't really a party for you out there.
A wise man once told me, "you can't paint a big picture with a little paint brush" and these parties have been trying to appease the most people, while disenfranchising millions as well.
