Feeling too lazy to investigate this right now. Anyway, comparisons don't always work. Circumstances change with time. History lessons are fine. But, only if you learn something from them. What I know is that no two issues are exactly the same.
Trump really expanded his executive powers and strengthened his judicial influence with this big senate victory outcome.
With Bob Corker, Jeff Flake and John McCain out of the way he replaces 3 thorns in his side with 3 loyal Senators. It is basically now The Trump senate. Alabama will almost certainly flip red in 2020 btw.
He might see some push back from Murkoski and a self aggrandizing, egotistical Mitt Romney but beyond that he will not see much opposition to his agenda in the upper chamber. Perhaps an occasional virtue signaling barb from Ben Sasse.
Jeff Sessions is out with more people in his cabinet to come. With a likely 54 seat majority in the Senate, confirming that pit bull D.A. replacement he desires should not be an issue.
And that is not even getting into the judicial branch.
Trump should have zero problems replacing Ruth Bader Ginsburg with exactly the justice he wants. That potentially tilts the Supreme Court to his advantage 6-3.
If he replaces 80 year old Breyer it goes to a 7-2 tilt.
And that is not even taking into account all the federal judges he and McConnell will push through, transforming and shifting the courts for a generation.
Would a House victory have been the cherry on top? Sure it would have, but Pelosi is now the face of the Democratic Party and people will tire of non-stop hearings and lack of an agenda rather quickly. As I stated earlier, a Pelosi lead House likely helps out Trump's 2020 prospects even more than a GOP led House.
