I have no idea what the Ds will manage to do.
I couldn't stand BHO, and I think the ACA (commonly known as Obamacare) is a terrible piece of legislation that didn't solve anything, yet I am a direct beneficiary of that bill, as it has contributed to the expansion of my business (how ironic that when I was raising questions during a local town-hall meeting held by the congresswoman from my district, the left-wingers from Park Slope were all over me when they found out that I'm a broker, yet I probably benefited from this law way more than any of them did). So, I can only hope that whatever they do won't be too damaging to the country, and whatever damage might be done, shouldn't last too long.
It's not that I think that everything they do or propose is bad, but with the level of political corruption, populism etc. we should be very wary of what might come. Thank G-d Trump was able to nominate 3 excellent justices, let's just hope that the Ds don't create some kind of judicial coup (like what was
done in Israel in the early 90s)
