Because in spite of the hysteria over this issue, the commission specifically requested only publicly available voter information. The same information that political parties buy from the states.
They finally realized that they had no legal basis not to comply.
I have seen this information when searching on specific names of people. Their party registration is in the 1st line of the search return and political contributions are online, also. Names, age, address(es). If they have homes in 2 states, that is also listed.
But who can say NY will send the public available list?
IOW, I don’t trust leftwing communists...
