Here is the short version for those that don't wish to read the long post: Bacardi is owned by assholes, if you need some rum get Havana Club.
Now on with the full version: Bacardi Martini and Flo-Sun Sugar are owned by two rich Cuban born brothers whose wealthy family lost quite a bit of land during the Revolution.

These two brothers, through their corporations, gave $1.44million in campaign contributions during the 2000 U.S. Presidential Election (no numbers yet, for 2004). This "contribution" pretty much gave them free reign to dictate U.S. Policy towards Cuba. A position which they use to stop any attempt of normalizing trade relations with the struggling island. Bacardi was also the main instigator of the 1996 Helms-Burton law. A law which tightened the US embargo on Cuba.

The person now in charge of enforcing the Helms-Burton law is Mr. Bush's top Latin American diplomat, Otto J. Reich. He helped write the Helms Burton bill and also worked as a paid Bacardi lobbyist from 1997 to 2000, according to the Center for Responsive Politics. He is reported to have received a fee of $600,000 from Bacardi for his services.

All this meddling with the government and the guys aren't even U.S. Citizens, they changed their citizenship to Spain, but live in West Palm Beach, Florida (a shady tax scheme no doubt).

Of course none of this is "new" information, I just got tired of telling people about it.
Now that it's written down and online I can just point them to it, and save my breath for other speeches.
