I would suggest this....if the blue wave doesn’t happen, and five Democratic Senate seats fall to the GOP, then the 2020 election becomes highly interesting.
It’s possible that the GOP could pick up three to four additional Senate seats in 2020, and even five or six additional governor seats. By 2024, you’d see at least three Supreme Court seats flipped over. If you were a Democrat....it’s a harsh reality ahead.
And there is exactly the answer.
They know that Ginsberg is going to croak soon, Bryer is likely to leave or die. Those two departures would leave the democRATS with Kagan, and the "Wise Latina".
That is why the left is soooooo desperate to remove Trump.
With a 7-2 conservative majority, the entire scheme that the democRATS have concocted will vanish.
