If I were the president

The key here is some ideas have some merit - though each has its own problems.

The problem is - as president you cannot just go around closing this and that and making this new program and that new program instead. Nor can you close a few doors and shift funding.

Congress controls the purse strings of the Federal Government. So pretty much anything you would want to do - goes through them. Good luck on the ATF, HS or anything else - because those all boost special interest money into the politicians re-election campaigns.

The office of POTUS is best used as a bully pulpit to accomplish things. Historically - speaking in the "modern" era where communication is instant and widespread, that has been how it has been most effectively used.

Want to get things accomplished - you have to be able to convince the people that this is important enough for them to raise the roof calling their LOCAL representatives. Only in that way can you exert any real leverage over congress.
