There isn't an ideal political party. I could come up with what would please me, but it wouldn't please my neighbor. No matter what we come up with, there will be disagreement.
For example, I am conservative in some ways and liberal in others. I think more should be done to help the poor in my own country (JOBS), but I believe abortion to be wrong. I despise wealthy people who complain about taxes and are stupid enough to think people are getting "rich off welfare", but I don't believe in a welfare state.
My ideal political party would ban abortion, create jobs in my country and give a hand UP to those who need it -- and not give a darn if a muliti-millionaire had to pay a few thousand more in taxes than he did last year. I'm not against being rich. I'm against being OVERLY rich and complaining about not being able to buy a third home or fifth yacht...
Others have their own issues. Many disagree with me on abortion and staunch Republicans would disagree on the rest.
The fact is that an "ideal" political party is just that: an "ideal".
