San Francisco Ballot Measures...

San Francisco approved ballot measures Tuesday to ban handguns in San Francisco and urge the city's public high schools and college campuses to keep out military recruiters. "Measure H" prohibits the manufacture and sale of all firearms and ammunition in the city, and makes it illegal for residents to keep handguns in their homes or businesses.

"Measure I", dubbed "College Not Combat," opposes the presence of military recruiters at public high schools and colleges. The proposition encourages city officials and university administrators to exclude recruiters and create scholarships and training programs that would reduce the military's appeal to young adults.

Okay. I know I'm just a lowly 1L, but can someone out there explain how a local ordinance can supercede the 2nd Amendment to the U.S. Constitution? Also, if the city bans military recruitment- of federal soldiers/sailors/airmen, can the federal government withhold federal dollars in funding?
