Think of what kind of energy you want to store in your crystal. We have tried charging our crystals with many different energies.

Some see the two-party system as a strength; as an advantage over the hopelessly fragmented multi-party systems of some European nations. But there are drawbacks as well. For example, multi-party systems force the parties to work together, to form coalitions. The two party system leads to polarization of opposing viewpoints with no room for a more centrist approach. The real world is too complex to be encompassed by a single line with liberals on the left and conservatives on the right.
