Voters will almost certainly get a chance this November to decide how long they want the city’s elected officials to serve — two terms or three.

There’s little doubt among political insiders that fed-up voters will opt for the most restrictive option available.

What’s not so clear is what happens if the Charter Revision Commission decides to place just a single question on the ballot that combines term limits with non-partisan elections.

Mayor Bloomberg led the push to get rid of party primaries in 2003 and was so soundly rebuffed at the polls — the margin was an embarrassing 70-30 percent — that he didn’t bring up the idea again for a half dozen years.

Insiders predict the result won’t be any different this time around.

But what if voters have to accept non-partisan elections in order to get stricter term limits? Then what happens?

“That’s the $64,000 question,” said one official.
