For over 170 years the Republicans and Democrats have ruled over this country, 100% of the time
That's because their party platforms are 180 degree polar opposites.
What do you propose instead of people taking a stand on one side or the other?
I'm 100% not a Democrat and I'm not an EVERYTHING GOES libertarian, so I vote for the best Republican I can
That is the problem, that the 2 parties are actually NOT 180 degree polar opposites, but instead are identical.
For example, the 2 real main choices for health care would be public subsidies, either for individuals to be able to make payments after the treatment, or for government to make the payment collectively for them. Insurance companies should have nothing to do with health care. But yet both democrat and republican parties both only support private health insurance, the one way that does not and can not work.
Another example are wars. Wars are terrible and illegal, and can only be justified in defense against an attack on the US. But all the wars the US has committed were offensive, illegal wars of profits instead, like Vietnam, Panama, Grenada, Desert Storm, the invasion of Iraq, the invasion of Afghanistan, the destruction of the army of Libya, the US attacks on Syria, the illegal economic sanction against Iran, Russia, etc.
Both parties are criminal in their support of illegal wars or military action.
I respect liberal and conservative positions, but neither party has been liberal or conservative.
But the fix is easy.
All we would have to do is skip the primary election, have just one with all the candidates, and let voters rank them all.
Then parties can be ignored, as they should be.
