So think about who does what in this country. The Democrats have the government jobs, post offices, schools, gas stations, many clerical jobs. What essential segment would would the conservatives shut down?
You are quibbling.
Revenue to those above you mentioned. Inconvenience to those on the dole (no goods to buy from shops that are closed, or from distribution companies/truckers who say "no more").
Not all government employees are dems, but the majority of them, at least in the civilian sector, are.
Gas stations? Most gas stations are small businesses.
