The one constant in a two-party system is that if one party pushes a limit while in power, and no one stops them, the other party will push the same limit the next time they are in power.

If your people are in power, before you ask them to push limits, you should ask yourself if you're okay with the other party also pushing those same limits to do things that they want done. 

And that question is inherently a hypothetical question. If you can't think in hypotheticals, you are completely unprepared to cope with a two-party system in a society of laws.

If too many of us laugh at hypothetical questions rather than consider them, then too many of us are unprepared to deal with a two-party system and a society of laws. If this continues, we will have a lawless one party system before you know it. The people will have let the incumbents push the limits so far that finally the incumbents will have the power to rig elections or stop elections, effectively locking in the one party lawless state. And don't misunderstand, there will still be laws for a common people in common situations, the part that will be lawless is how the leaders and their friends are allowed to behave. "For my friends, everything. For my enemies, the law."
