The original offers a choice between the Polish political parties PiS and Platforma. I've taken liberties with the translation to make the gag a little funnier for Anglophone readers who might be following the US election.
The original says, on the left, "The president is a cloddish rural unsophisticate" (there's no precise equivalent in English of the Polish word cham) and on the right "I love the president!" I believe it refers to a recent Polish president who was thought of as crude and boorish. I've attempted to give a version that works in English.
For other political Racz cartoons that can be read as comments on the US, or indeed almost any, election, see here and especially here.
