An IRS PIN will be perceived the same way showing ID to vote is considered voter suppression. The elderly, the poor, the minorities will be thought unable to know how to get a PIN and worse, remember the PIN. Democrats will claim it will discourage access to vital information. Criminals are always only one-half step behind new security measures. Cracking a PIN by algorithm or confiscating it would take the hacker geniuses in China, Russia, N.Korea and Silicon Valley about a week and another week to have the results on the dark web.
