They aren't trying to require ID. They are trying to require either a passport or birth certificate. A lot of people don't have a passport, and a large percentage of the population does not have a birth certificate readily available. It takes money and time to get a replacement copy, and even if everyone requests one in time local agencies will be flooded such that the delay will cause them to be unable to vote. It is already well known that the way things have been done for many decades works just fine, and all claims of election fraud have been thoroughly debunked. Also, a poll tax is illegal, and it cost money to get any of the three (ID, Passport, Birth Certificate.) It's ironic that you are complaining about election fraud while supporting installing the means for Trump to commit it.
