In general, the GOP has not put up any meaningful resistance against Obama on anything so why should he reign in the abuses? When you let something slide, you can expect a lot more of the same.
The impeachment initiative is too little too late IMO.
I think what exists is simply a one-party system...set up like the WWE-wrestling empire. They talk up fake frustrations and point fingers at various pretenders. The President is every bit the character of Bush. It’s great reality TV but it’s all fake.
