Why do republicans try to suppress voting and then say they represent the American people?

In almost all Republican states there is some effort to suppress voting. In Texas the governor removed many ballot drop boxes to where there is only per county. That’s one box for 4.7 million voters in one metropolitan county, an obvious an attempt to suppress where democrats do better. In California republicans put illegal drop in places like gun shops and churches. In many big cities across the country threatening phone calls went out to voters saying will be surveilled by the police and the IRS. Trump says he wants his minions to show up at polls to check voters.

If you represent the American people wouldn’t you want all eligible voters to vote. Or just the ones you think will support one party?
