I'm not saying you're wrong, Oli, but FFC was clearly "mixing metaphors" all through GFII. The Valachi hearings did occur in '63, and the charts shown in the movie were perfect copies of the charts shown then. But, McClellan held hearings about organized crime racketeering from '57 through '60. Meyer Lansky, the obvious model for Roth, was rejected by Israel in '72 and landed in Miami after that, but he never suffered a stroke or attempted murder on New Year's Eve, 1958-9 (I don't think he was even in Cuba that night). I'm basing my surmise about Roth returning "to vote in the [1960] election" on the statement he made in his Havana hotel room to Michael: "Just looking for one man who wants to be President, and having the cash to do it."
