No way will this go against democrats. Mueller is doing a couple things with this indictment.
1) He’s throwing a hail mary pass hoping to get attention off Uranium One and his involvement (along with all the other rats involved).
2) He’s trying to put pressure on someone to turn against Trump. Even if they lie to get Trump they don’t care...they want to show that this person will be bankrupt and has no real way to challenge the federal gov’t. Even if they aren’t convicted in the end they will lose millions. All they need to do is lie about Trump to make this all go away. That’s why he’s going to arrest him and not do a simple turn yourself in procedure.
I agree, Mueller is so far in the bag for the Clinton, he’s never get out, except feet first. Hillary has his number.
