Net result: Republicans expanded their control of the Senate while the Democrats took control of the House. The bottom line is that there was no blue wave, essentially there is no backlash against Trump’s first two years in office.
Random thoughts in random order.
1) The Democrats overplayed their hand on Kavanaugh, showing that #metoo has limits. I didn’t really understand the intense opposition to Kavanaugh, he was as good as we would get with Trump and a Republican senate; that battle had already been lost in 2016. Sun Tzu teaches that if you want to win a war then you must choose your battles carefully. This is a lesson that the Democrats never learned. So the Democrats wasted their political capitol on a battle that was never winnable, energized the Republican base in the process, and it cost them some seats in congress.
2) Democratic leadership is not very likable. Every republican running for the House ran against Nancy Pelosi. She is a lightning rod (it is insignificant if rightly or wrongly). She is an astounding 78 years old, how can she be the face of the future?
3) Trump is smarter than we give him credit and his base is passionate. I have no idea what Trump believes in, I’m not sure that he knows, but he has re-shaped the Republican party in his image.
4) As of right now, I don’t see anything blocking Trump’s re-election. It would seem the Democrats are lining up a clown car of Septuagenarians and Octogenarians to challenge him in 2020. I am old enough to remember when the Republicans were the party of old stodgy people, my, how times have changed.
5) Our government is based on the checks and balances of 3 parts of government. Unfortunately the legislative branch has ceded its power to the executive. This imbalance makes us wobbly at best and headed for a serious crash at worst. Trump is not the problem, he is but a symptom. We need to fight the disease while managing the symptoms.
