If you’re a Trump supporter, take a moment to consider these points.
1.) If he were doing as badly as the media wants you to believe, they wouldn’t be this rabid. They’ve been short-circuited this entire election cycle and it’s showing. If you start to feel demoralized by their outright lying, disconnect from them.
2.) Trump has done well to this point but his victory is by no means certain. So while it is to your advantage to tune out the detractors, do not tune out when he requests your assistance. He has to upend the iron rice bowls of the existing power structure on both sides to restore true representation and he’ll need some help.
3.) In the future, skepticism of all leadership is an absolute must. As this election season has demonstrated, they might not be who you thought they were and require a complete write-off. I don’t miss a lot of the people I’ll never be fool enough to believe again, and recommend that approach to you.
4.) There is no practical distinction between Republican Establishment and the Democrats. The fact they sound the same as you do until it matters is immaterial. If you can’t primary one that absolutely must go (see Paul Ryan), purge vote them, because it concentrates the opposition to one party instead of leaving it infesting both of them. There will be no true second party until you insist on it with your voting and rule out the alternative.
Keep calm and carry on.
