I've purposely avoided the "thoughtful and intelligent debates" section because I don't consider myself either. But couldn't resist this one. I may need to add to my list from time to time.
I would submit a budget that could be passed. Something our current dear leader has been incapable of doing.
I would eliminate the IRS and institute a reasonable flat federal tax on all purchases. That rate would be set in stone and could not be raised arbitrarily. That would eliminate lobbyists and thin the herd of lawyers.
I would defund the war on drugs as it has been an unmitigated failure. Plan to release all non-violent drug offenders from prison. Along with that I would offer for sale some drugs legally through pharmacies. Free treatment programs with a 3 time loser provision. Fail three times and you go to prison for a year. Prison would not be a gym and tv room environment. It would require real work.
I would make welfare available only to those who TRULY cannot work and require drug testing to qualify.
I would end all goverment subsidies to corporations.
I would seal the borders and reform immigration policy to allow only immigrants who can contribute to society, not just to democrat voter roles. All those here illegally would have 90 days to register and start a track toward citizenship. Fail to register, you would be rounded up and deported. Those who register would have to pass a criminal background check to qualify.
I would require mandatory service of at least 2 years in the military or other useful govt service. National Parks, Forest Service, etc.
I would issue federal carry permits for those wanting them without a criminal record or history of mental illness. Commit a crime with a gun and go to jail for 10 years, no parole.
I would remove crazy restrictions on domestic energy development.
While i think education decisions should be left to the states, I would strongly encourage governors to require real achievement to pass from grade to grade. Those who clearly have a limited academic potential would be offered trade school training as an alternative.
On my second day, I would pass a national law stating that Croutons could be no bigger then 1/4 inch square.

Thanks nosmoke, I like that one.
