Giuliani hasn't decided on a run for governor.

(CNN) - Rudy Giuliani fueled speculation Wednesday he is considering a run for governor with a high-profile op-ed in the New York Times, but the former mayor told reporters he hasn't decided one way or another on a potential run just yet.

In a conference call Wednesday morning, Giuliani denied the op-ed - in which he proposes a series of measures to fix the state's gridlocked government - was meant to be a signal he is actively interested in running for governor in 2010.

"I know how to send signals, if I wanted to I would do it." Giuliani said. "I am not leaning [in either direction]."

In the op-ed, which Giuliani says is "not a partisan criticism," the former Republican presidential candidate calls for a statewide constitutional convention to institute a series of reforms, including changes in the budgeting process, term-limits for law makers, and campaign finance reform.

Two polls out this week show Giuliani would easily top current New York Gov. David Paterson in an election match-up, but would face a considerably more challenging bid against the state's attorney general, Andrew Cuomo.

Giuliani largely withheld criticizing Paterson directly Wednesday. "There is enough blame for all to share," he said.
