Yep. You may not like Trump, but look at the alternative. And Biden has a HIGH chance of naming Hillary as VP. So Biden wins the election, is declared incompetent, and Hillary becomes president, with socialized healthcare, universal income, much higher taxes, many lost jobs (especially low-skill jobs), and many more closed small businesses. 99.7% of business in the US is small business with 500 or less employees.
Anything that hurts small business hurts the vast majority of Americans.
