Found at the Federal Election Commission, Dan Cooper of Cooper Firearms of Montana did indeed donate $3300 bucks to Obama this election cycle, all in the primaries:
Add that to the $200 from OpenSecrets.org, and you have the amount listed in the USA Today article. Also, conspicuously absent is any donation to John McCain or the Republican National Committee. Pretty clearly Cooper Firearms of Montana is worried about damage to their business. They ought to be. Selling gun rights down river isn’t something we pariticularly appreciate. Just ask Jim Zumbo.
