The Bush "Non-defense discretionary programs" that you list above includes Homeland Defense type spending.
Your statistics are misleading.
Not true. You've offered no evidence that my data is bogus. It comes from OMB.gov, the historical tables. I used simple math to figure out what was spent. Straightforward computations. Homeland Security spending is a drop in the bucket. About $30-billion/year. It doesn't change the results. Besides, there was also spending by Reagan on homeland secutiry in his budgets. They just didn't have a HSD back then. OMB breaks those figures out in their spreadsheets going back to 1940. Check it out.
