Ted Cruz has said if elected the IRS will be shut down!
Well, he can say that, but his plan includes an income tax and a Value Added Tax. No way.
One good reason to lay about with a scythe on alphabet-soup agencies is that hundreds of thousands of 'Rats hide out there, burrowing in and feasting off the work of others while doing political oddjobs like Lois Lerner and James Hansen and Joe Wilson.
The only way to get rid of all the 'Rats without violating the Civil Service Act (and thus undoing all the illegal political organizing the 'Rats have done since the Klintonx came to power) is to shut down the agencies and subject all its employees to a general RIF. The agencies' responsibilities must be moved (if it is desired to keep them), and the "perps" left behind in the dust to go crying on their knees to their former Obamarrhoid masters.
Cruz has it right. The executive departments most loaded with 'Rats are the ones he has named for closure, and that's the right thing to do. Somebody has to delouse the government and return it to some semblance of political neutrality, and that includes the DoD.
