Why are we spending money on these?

From the PowerLine which cites to a London Times article, some of the items in the recently passed omnibus bill:
- Removing tattoos from gang members (California): $200,000

- Polynesian Voyaging Society (Hawaii): $238,000

- Swine odour and manure management (Iowa): $2m

- Preserving Lahontan cut-throat trout (Nevada): $250,000

- Stable fly control (Nebraska): $866,000

- Blackbird management (North Dakota): $265,000

- Encouraging teenagers to abstain from sex (Pennsylvania): $24,000

When we are going to be running an almost $2 Trillon dollar deficit, why are we spending money on these items? Sure they are small, but in the aggregate, it still adds up to $2 Trillion dollars. Used to be that 2 Billion was incomprehensible. Now we bandy about a number one thousand times greater but without one thousand times greater concern.
