See what you can get by putting some subtle feelers out. Talk to a recruiter or two. Best time to search for a job is while you have one, but you don’t have to commit to it full time unless shit really hits the fan. You’re more likely to get written up than fired initially anyway if he’s not the owner, erratic or not he has to answer for that.
Continue working towards whatever certifications you want in the meantime, especially if the job pays/reimburses you for it.
The problem with this argument is it only works for people who show up to vote, and if the Dems don’t get people, particularly young people, inspired enough to do so, then they’ll lose. Fear only works as a motivator for so long, at some point, you need to provide a carrot and not just the stick.
