He's clearly away for longer than a month as he sees in the new year in Havana.
Roth's comments about the election is no guarantee that the election were close by.
The timeline in the GF films is always up to scrutiny.
If we choose to use Roth's absentee ballot remark as a guide, we first have to know in which state he was registered to vote. Was it NY or Florida? It was probably Florida. Apparently, Florida did not have early voting until 2004, but it may have had absentee voting since 1845. There is no indication how early a Florida resident may request an absentee ballot, so we don't know when his request would have been denied and therefore we don't know from that when he returned to the US.
