Who’s in, out and in between? Chances are this will be out of date minutes after it’s been posted, but here’s the state of the race as of Monday night:

-- City Councillor At-Large Felix Arroyo is expected to throw his hat into the mayoral ring on Tuesday. Commonwealth magazine’s Michael Jonas noted the news first on Twitter. His entry will likely mean more candidates angling for one of the four City Council At-Large seats.

-- Former Phoenix political reporter David S. Bernstein says he has multiple sources telling him that Robert Lewis Jr., a former official with the Menino administration and the Boston Foundation, will not run for mayor.

-- The Herald, citing a source close to former City Councillor At-Large Michael Flaherty, says the 2009 mayoral candidate will pass on another bid and instead attempt a return to the City Council.

-- The Herald’s Peter Gelzinis throws John Barros’ name into the mix. Barros, who is Cape Verdean, is the executive director of the Dudley Street Neighborhood Initiative and a member of the city’s School Committee. According to his biography on DSNI’s website, he is also the co-owner of Restaurante Cesaria, a local Cape Verdean restaurant.

-- City Councillor At-Large John Connolly, first major candidate to jump into mayoral race, has a campaign headquarters: It’s in Roslindale, on Belgrade Ave.

-- The mayoral campaign of State Rep. Marty Walsh (D-Dorchester) is planning an organizing meeting later this week. The 6:30 p.m. meeting is set for Friday, April 12, at McKeon Post on Hill Top Street.

-- Southwest Boston appears to get another candidate interested in succeeding Mayor Thomas Menino: Hyde Park’s John Laing Jr. opened a campaign finance account on Monday, according to the state Office of Campaign and Political Finance. Frederick Newton of Dedham is listed as his campaign chair. Laing Jr. did not return voicemails requesting comment on Monday.
