Criminals walk every day. And bannon defied the subpoena just to give people the finger. All he had to do was show up and refuse to answer the questions. To go to a Grand Jury over a misdemeanor charge that would be a slap on the wrist and a possible fine is pretty ridiculous. Just wait until the Republicans are back in power and they will be. When that happens there will be plenty of Democrats defying subpoena's as well. It's going to be a bunch of tit for tat.
Go after bannon for something that will send him to prison like tax evasion or wire fraud for all the money he's fraudulently raised and spent like a drunken sailor.
All this nothing burger for defying a subpoena is doing is rallying supporters that are convinced it's nothing but a witch hunt. If you want to take a bite make sure it's worth chewing and not just a nibble that still leave you hungry.
So if Obama defies a congressional subpoena after the Republicans take control of Congress do you want him thrown in jail as well?
There's also a thing called due process and bannon has his right to a day in court whenever that may be.
The tit for tat started with the Republicans who were trying like hell to impeach Clinton prior to the 2016 election for years. And the Democrats sat through all those stupid as shit hearings and followed the law even though the now shown to be insurrectionist, Russian linked Republicans had tried to force them into a corner of not listening to subpeona's and breaking congressional norms (like McConnell did when he refused to sign off on a bi partisan response to Russian attacking our democracy in 2016 when it became known).
The thing is that there is no 'both sides' to this lawlessness when it comes to the 2 major political parties in our nation. And it is shown when the Republicans do stupid shit like try to indict McCabe for doing his job and the grand jury looks at the evidence and laughs Trump's lawyers out of the room.
Bannon already had his 'right to a day in court' and got found guilty and was pardoned by Trump (because again lawlessness Republican morality). Pretending like he shouldn't be held accountable for other ways he has tried to scam/ aid in the attack on our nation is not something I agree with.
And pretending like somehow this is going to blow back on the Democrats is just full on bullshit.
