Okay, can someone talk me out of my rising panic?
What can any of us do except stand by and watch this unfold? It really feels like protests, phone calls, petitions, donations to ACLU, etc. aren't going to be enough.
My SO and I have been talking about this extensively. Executive actions aside, changes aren't going to be immediate. The Framers made sure that enactment of new laws took time (particualrly through the Senate) exactly because they didn't want a single President (and by procedurals the majority party) to have unfettered rule.
One thing I think is very important is to keep contacting your Congressional representatives. If they are GOP even better. The best immediate resistance to the executive branch is the legislature. If those folks feel their re-election is in danger in 22 months they'll (eventually) find their balls and start standing up.
If your representative isn't actively speaking out, give money to the opposing candidate(s). If he/she does speak out, support them (they are going to need it)
This goes for your state governor too. State governors and state governments are responsible for handling voter registration and voting procedures.
Stay active, stay outraged. One of the factors that got us here is that too few people payed any attention, and too few people actually voted. This may be the hardest thing to do for the American public, and at the heart of DJT's strategy is most likely the bet that the country won't be able to stay tuned for very long.
Participate in voter registration drives NOW. DJT (and to a lesser extent the GOP) is already making noise about tightening up voter laws.
<60% of voting-age citizens turned out in November, and the number of registered voters has been in decline for decades. But most accounts if >60% of eligible voters turned out on election day this result would not have happened.
In two years DJT's powers will either be curtailed or expanded. In four years we'll either have a new president or a re-affirmation of everything he has done and will do between then and now.
