It is “rak”, not “rah”. The second letter is a “koof”. The word means “only”, as you surmised: “Only Netanyahu, only the Likud”. The piece of paper looking thing is the code pronted on the tocket that voters reauest in order to vote for the Likud, Netanyahu’s party. The coded papers are a throwback to the early years of the State of Israel, when mamy people didn’t speak Hebrew. To enable those voters to vote, each political party had a 1-3 letter symbol printed on its card.
Thanks for that explanation!
