I guess you guys just thought you would be in power all the time.
The bottom line is this: When designing your form of government, it is best to assume you will be out of power more than you are in power...or at least a 50-50 split. And don't try to limit checks and balances when you are in power so you can do good (as you define it), and then be shocked and dismayed when the other side does the same thing.
I was hoping Trump would wake you guys up, but I don't think you want a systemic fix to the problem you just called out. you just want to get back into power. You want Jamaica-Democrat politics, not neutral constitutional republic politics.
