Why didn't President Obama pass any gun control legislation?

The president does not legislate or make law. Obama was President under Republican influence. These men very explicitly explains their top priority was obstructing him at every chance. Nothing gets done in a climate like that. Attempts to limit the size of gun magazines, expand background checks of gun buyers and ban gun sales to buyers on terrorism watch lists all failed to pass under Obama.

No gun legislation is being passed right now because nobody in government is listening to the majority of US citizens, who do want some kind of regulation. Sadly, we don't have as much money as the NRA.
