So far, two of the gubernatorial candidates – the Democrat and one of the four Republicans – have announced their preferred running mates in advance of their respective nomination at major party conventions.

Former Rep. Rick Lazio made his selection of Chautauqua County Executive Greg Edwards known far in advance of both tomorrow’s Conservative confab and next week’s GOP get-together.

Conservative Chairman Mike Long has already signaled his support for the Lazio-Edwards ticket, and it’s expected that the duo will get the nod for Row D tomorrow (although, with the way things have been going of late, nothing’s done until it’s done).

AG Andrew Cuomo took the wraps off of his super-secret LG selection, Rochester Mayor Bob Duffy, just 24 hours before his scheduled convention nomination. Duffy was nominated that very day by his fellow Democrats, but didn’t show up until this morning – along with Cuomo himself – to give his acceptance speech.

That leaves Suffolk County Executive Steve Levy and Carl Paladino still without running mates. And, as it turns out, they will both be flying solo at tomorrow’s Conservative convention.

That makes things a little tricky, although the party could nominate a placeholder (preferably someone who plans to move out of state soon, or an attorney itching to become a judge), and go back to fill that in later.

“Steve is still having discussions with potential candidates and will be making an announcement soon,” Levy campaign spokesman Josh Hills told me earlier this afternoon, adding that “soon” does not mean before tomorrow afternoon.

Ditto for Paladino, whose campaign spokesman Michael Caputo, said the candidate has been interviewing potential No. 2s, but won’t be making a final choice before tomorrow. I also haven’t heard anything of yet from M. Myers Mermel, who, until just this Monday, was an LG contender himself.

There has been a lot of speculation that Levy might tap a woman to run as his LG, which would make him the only statewide contender so far with a female running mate. (There are currently no women on the GOP ticket).

Paladino met back in April with former NYC Council Minority Leader Tom Ognibene to discuss, among other things, his LG selection. I’m told Ognibene may yet play a role with Paladino’s gubernatorial bid, but won’t be his No. 2.
