(This was about 2018~worse is coming for 2020. Neither Texas Democrat candidate who suffered raised a peep about this abuse)
There's an uptick in overseas ransomware attacks in 2019 increasing county voter rolls vulnerability on Election Day 2020; they could be dry runs for hackers hoping to maximize chaos, ranging from taking voter rolls hostage to shutting down electricity in polling places, plus voting machine incursions. Many states haven't the resources to share with counties to beef up systems or provide the necessary human resources for election officials trained in security measures., plus the problem of 3 elections companies having control on the market and none of them being subject to much in the way of federal control over security. Some even use key components from China, which could be pre-hacked.
