Israel's president 'ashamed of grubby campaigns' as hotly-contested election begin
"We don't deserve another awful and grubby election campaign like the one that ends today and we don't deserve this never-ending instability. We deserve a government that works for us," Rivlin said in a statement after voting in Jerusalem.
The head of state did not spell out which aspects of the campaign he found troubling.
But the run-up to Israel's third election in less than 12 months has included a series of leaked recordings and mudslinging.
The left-wing Haaretz newspaper said in an editorial on Monday that the campaign "broke all known records for slime, filth and bile".
Rivlin said voting day in Israel "is normally a festive day".
"But the truth is that I don't feel like celebrating. I only (feel) a sense of deep shame when I face you, my fellow citizens," he added.

Voters are seeking to end a grinding political deadlock following two inconclusive elections in April and September.
Polls have pointed to another tight race between Prime Minister Benjamin Netanyahu's right-wing Likud Party and the centrist alliance led by ex-military chief Benny Gantz.
Both sides are expected to fall short of the 61 seats needed for a majority in parliament and will have to strike deals with smaller parties to forge a stable coalition.
That proved impossible after the last two votes and a further stalemate remains possible, raising fears of a fourth election before the end of the year.
"I ask you to go and vote," Rivlin said.
"I very much hope that we meet again only in 2024, or at least that I won't see another election campaign as president of the country that is so dear to us all."
Rivlin cast his ballot in Jerusalem shortly before Netanyahu, who is seeking re-election under the weight of criminal indictments.
Turnout has emerged as a key factor in the race with fears of the coronavirus outbreak and voters growing tired of the Israeli electoral process.
