The MILITARY is the Left's easiest target.
Repelling the Invasion from Mexico is their second easiest target.
The proper teaching of ENGLISH, mathematics, science, and history to American students is their third target.
The Left has plenty of easy targets they wish to cut from the national budget. If you can identify something that's both constitutional (the education example was not) and beneficial to Americans in a way that increases personal independence and self-reliance, they want to cut it.
