Impeach Obama? Ain't gonna happen. I don't care how bad these scandals are, and they are really bad, we are stuck with Obama for the duration. Practically everyone in media, entertainment, and academia voted for Obama, and if you voted for Obama you most likely: a) don't know about the scandals, b) would never admit you screwed-up, c) say, "what difference does it make?", d) think it's all Bush's fault, or e) all the above. This makes impeachment and removal impossible.
There is another way to act decisively; just avoid paying taxes. If you are among the informed and intelligent minority who believe Obama should be removed, if you believe he used the IRS like a Gestapo to kill dissent, if you believe he abused his power, if you believe he used the DOJ like a KGB to spy on his detractors, if you believe he lied when he knowingly blamed the Benghazi attack on an innocent videographer who still sits in jail to this day, then you should defund him. Go Galt, invest in tax free municipal bonds, barter, live off your assets, go off the grid, start a non-profit (you may want to think about that last one), tell your Congressman to defund him. Do everything you can to legally avoid federal taxes and defund Obama. That's the only way.
BTW, break no laws! We can defund Obama legally if we work together. You will never eliminate all your taxes, but you can certainly avoid a bunch if you make changes. Remember, GE pays no taxes and breaks no laws. Of course, you will never have the advantages of government access and legal advice that Obama's friend GE has, but you can probably cut your tax liability with some effort. Make the effort. Defund Obama. It's all you can do, unless you're content with just fuming.
