Why play the game of picking and choosing winners and losers? Pick a percentage and order the cut across the boards. Let the department heads and middle managers decide how they are going to get to their funding allocation.
That's a target to hit.
Simply going after the employees won't touch the grants since the Executive will take existing authority and transfer it to another "agency" ~ maybe the National Security apparatus.
Outside of Food Stamps, USDA (Department of Agriculture) has over $100,000,000,000 in grants and "program" funds available every year.
Just two agencies and I can come up with GRANTS equal to half the entire federal employee salary totals.
You guys spend 10 times the effort in getting rid of a handful of federal government workers.
If you are serious about cutting the cost of government GO AFTER THE GRANTS!
