Trumps lying about China, information is available for sale by our own government, they are just trying to push for more voter suppression since they can’t win the popular vote.

So apparently the information Trump is claiming that the Chinese gained accessed to can be purchased for less then $70k. He is using this to push laws to restrict voting. Republicans constantly lose the popular vote and still end up winning elections based on gerrymandering and voter suppression. The save America act is just another example of this. In most states to register to vote you have to apply and provide proof of citizenship. So illegals cannot obtain the ability to vote for federal elections already.

After the 2000 presidential election and the resulting Bush v. Gore Supreme Court decision, Congress passed the Help America Vote Act (HAVA) of 2002_of_2002). HAVA legislation created the U.S. Election Assistance Commission. The legislation also directed every state to create “a single, uniform, official, centralized, interactive computerized statewide voter registration list defined, maintained, and administered at the State level that contains the name and registration information of every legally registered voter in the State …”[2]
These digital databases are known as voter files, and they are essentially a record of the registered voters in each state. Voter files typically contain voters’ names, addresses, and a record of the elections they have participated in. They may also contain ages, phone numbers, email addresses, political party affiliations, previous political donations, and other consumer data, depending on the state.[3][4]
The information in a state’s voter file may indicate whether someone has voted in a given election or which political party a voter included in their registration (in states where this is required). However, voter files do not indicate the candidates and/or political parties that voters have cast their ballots for in previous elections. This information is not publicly available.[3][4]
State voter files are digital databases that contain information about thousands of voters, so they can be helpful resources for political parties, campaigns, pollsters, academic researchers, and journalists to study. For example, studying the demographic composition of the electorate may help to predict the types of voters that tend to vote early or by absentee ballot, the types of voters that tend to show up for primary elections, etc
