Nothing Democrats can do about it. McConnell will get his 6-3 Supreme Court and even Roberts will not be able to contain the Conservative Court.
Democrats have learned that elections have consequences and what matters most is getting your way, not doing what is right.
So what can Democrats do if they win the White House and Senate in November?
There is much talk about packing the court and expanding seats. But I think that is excessive. What they should do is end the filibuster in the Senate.
Democrats should immediately:
1. Repeal the Trump Tax Cuts
2. Pass effective Gun Control
3. Expand Obamacare and make it impossible to repeal
4. Pass Immigration Reform
5 Pass extensive Environmental Protections

Pack the Supreme Court like Obama did the federal courts so they win all their court cases and will do things like round up the guns and flush the 2nd amendment down the toilet.
Then add Washington DC and Puerto Rico so they can take over the Senate so that no GOP nomination ever occurs again and any GOP President that does not "behave" gets impeached.
