Biden got around 60 million and most of them was a vote against Trump. I believe most of us are Trump supporters first.
No matter what the final outcome is, stay in touch and get involved at the local level with elections. Someone made a great point that even in very strong Republican counties, elections are still run by Democrats.
Also, get involved with other local government offices and commissions. For example, I live in Fairfax, VA and you can actually try to get on local boards (most are voluntary and serve 1 or 2 years). Check your local government sites and look for these opportunities.
