Only obstruction is preventing indictment of all these DNC players.
There are MOUNTAINS of evidence against Hillary Clinton, Debbie Wasserman Schultz, FusionGPS, Bill and Hillary's pay-to-play selling State Dept influence in exchange for Clinton Foundation donations, Hillary's illegal private server and e-mails that compromised national security every day of the 4 years she was secretary of state. Using FBI, CIA and NSA to spy on the Trump Campaign, and post-election on the Trump Administration. The clear ethical breaches and crimes of James Comey, Loretta Lynch, Eric Holder, Rod Rosenstein, and the thoroughly discredited Meuller investigation that was created only by lies and corruption, and is stacked with huge campaign donors to Obama, Hillary and the DNC, and therefore clearly not neutral and objective. Lois Lerner and the IRS targeting conservative Tea Party groups and large GOP donors. On and on. All this evidence is RIGHT THERE waiting to be investigated and prosecuted. Federal agencies like the State Dept, DOJ, FBI, CIA and IRS are stonewalling those willing to investigate. All these are bureaucrats who clearly voted for Hillary, and are immorally abusing their positions to help the DNC and hurt Trump.
Those are the facts, for those willing to objectively look at them.
My only guess is that the establishment Republicans (1) don't want Trump to succeed and topple their power structure where they have more in common with the establishment Democrats than they do with their conservative Republican voters, and (2) they don't want to set the precedent of the GOP investigating the outgoing Obama administration, because eventually the Democrats will be back in power and then can do the same to them, and their GOP profitable earmarks, insider trading, and other sweetheart deal activities they don't want revealed. One hand washes the other, if we don't lower the hammer on you establishment Dems, you won't do it later to us establishment Republicans.
