The NRA is one of the reasons Bloomberg has dumped millions of dollars in to local elections. Sometimes his "grassroots" wins, others it gets smacked down real hard.
Unfortunately as we witnessed in CO. Having the votes in the legislature to steamroll any opponents, gun laws do get passed. The result, as mentioned before was 3 recalls. 2 lost at the ballot box, the other quit before a vote was cast.
Of course you could donate at the state level
