No s***, Sherlock.
Why would they be discussing the possibilities of becoming president of a foreign nation?
Apparently you don't know who the D-B's are.
1. THEY'RE CUBAN. Cuba is not just "a foreign nation" to them.
2. They've been working to get rid of the current government in Cuba.
3. Their family, IIRC, has a political history in Cuba.
4. When Cuba becomes democratic, many in the Cuban exile community will want to go back and help lead the country back to prosperity (don't even dare say "why would they . . .?"). Could that include the D-B's? I don't see why not.
I just thought I'd throw out a fun possibility, but thanks for trying to smack it down.
