No where near as bad as you imagine. They won’t be able to pass a single thing. Trump can pick up Obama’s pen. He will also be able to finish shaping the courts and get another supreme or two. Last but not.least he will have an enemy to run against.
I assume that next year the Democrats who run the House will refuse to appropriate sufficient money for:
1. the military;
2. Immigration and Customs Enforcement;
3. border enforcement generally, including restrictions on immigration from countries that send people who we cannot vet;
4. enforcement of various Trump Executive Orders, including one that denies automatic U.S. Citizenship to children of illegal aliens born in the U.S.;
5. U.S. Government litigation in defense of programs and policies that the Democrats do not like;
6. grants and loans to, and other cooperation with Israel;
7. enforcement of sanctions against Iran;
8. enforcement of tariffs and other trade measures against Communist China;
9. enforcement of laws against racial discrimination when the discrimination is against whites and Asians who are targets of an “affirmative action” program;
10. any program that seeks to undermine the proposition that human activity is causing the earth’s climate to change;
11. any program that encourages anything other than abortion as a birth control solution;
12. enforcement of anti-voter fraud laws;
13. any state that has a photo identification requirement for voting;
14. any state that prohibits voting by felons;
15. any state that allows electricity to be produced by anything other than wind and solar power;
16. any state that has restrictions on abortion.
Feel free to add to the list.
If the Republican-controlled Senate and Pres. Trump refuse to approve a budget that includes such monetary restrictions, there will be a battle as some Government functions cease because of the lack of spending authorization. The Democrats who run most of the dominant media will portray the House Democrats in the best light, and the Republicans in the Senate and Pres. Trump in the worst light. How long will the “shutdown” last?
Maybe the House Democrats will not do any of this. How far will the House Democrats go? How many flies will Renfield eat?
