JERUSALEM – After a lackluster three-month campaign, few doubt that Prime Minister Benjamin Netanyahu is on his way to re-election. But the makeup of Netanyahu’s next government remains a mystery.

If re-elected Tuesday, Netanyahu will face a critical decision that will define his term.

He can form a majority coalition with the hard-line and religious parties he often calls his natural partners – or reach across the aisle and try to bring centrist parties into a broader-based government that might be more amenable to pursuing peace and ending, at least partly, the occupation of the West Bank and other territories.
