SAN DIEGO - Nathan Fletcher has filed to run for mayor.
Fletcher, a former state assemblyman, filed a "candidate intention statement" with the San Diego City Clerk's office on Tuesday -- the day before a deal was reached by negotiators in mediation involving Mayor Bob Filner, who resigned on Friday.
Fletcher was not immediately available for comment.
The statement was posted on the city clerk's website. It will allow him to raise money for a campaign.
"It's not surprising he filed so quickly. You never let the grass grow beneath your seat when there's a snap election like this," said Mesa College political science professor Carl Luna.
In mid-July, Team 10 first reported at least 10 "high-level" Democrats met to discuss drafting Fletcher into a campaign for mayor.
The subject line of an email obtained by Team 10 read, "Draft Nathan Fletcher effort."
The email was sent to San Diego Democrats and Republicans, according to sources.
It read, "It is possible that he could decide to resign very soon and we would like to be prepared to immediately call for Nathan Fletcher to run for office," the email read.
"Timing will be everything if Bob Filner resigns," the email continued, "we would like to have a letter ready to send to Nathan that calls for him to immediately declare as a candidate."
"This would allow him to say that he has received a letter from a bi-partisan group ... To learn that Nathan Fletcher has your support might discourage others to run," the email read.
Sources said Fletcher did not attend the meeting.
Political experts believe Democrats will lean on Fletcher, who switched from Republican to Independent, and then to Democrat.
"The Democratic Party won the mayorship for the first time [in] decades. They don't want to lose it; Nathan Fletcher is probably their safest best," said Luna.
The other person to file paperwork is businessman Tobiah Pettus, a conservative who ran in 2012.
The man attracting the most speculation is former councilman Carl Demaio, who is running for Congress.
Late Friday afternoon, his campaign manager said he's been conferring with supporters and will mull over his options over the weekend.
San Diego City Attorney Jan Goldsmith, who scored the most favorable ratings in a recent 10News poll, told 10News Friday, "I'm not planning on running for mayor."
Other names being talked about are incoming interim Mayor Todd Gloria and Councilman Kevin Faulconer, who said he would make a decision in the next 4 or 5 days.
Meantime, sources told 10News labor groups have reached out to Assembly Majority Leader Toni Atkins and Councilwoman Marti Emerald to see if they would be interested.
