I tried to figure out why on earth these IRS people would target political groups based on ideology. My experiences with the IRS have made me believe that it's a remarkably professional organization. I can't imagine what would cause them to care about the political orientation of their victims.
Duh! I slap my forehead. As reported, there was a huge increase in non-profit companies leading up the the last election. The names and keywords they looked at clearly indicate the likelihood of illegal political activism. How else would you do the first selection on targets for investigation.
"Tea Party" and "Patriot" are usually included in the names of political action groups. It's as if these people are being criticized for looking at non-profits with names including "Republican Action Network".
