The Boston political operative who ran former City Councillor Mike Ross's campaign last year is taking a job with Putnam Partners, a Democratic media consulting firm in Washington, D.C. Cayce McCabe, who jumped to the Ross campaign after running state Sen. Linda Dorcena Forry's First Suffolk District campaign in 2013, is signing on as a senior associate.

McCabe announced the move in a mass email. McCabe will keep advising a candidate, Evandro Carvahlo, who is running to replace former state Rep. Carlos Henriquez, through the April 1 primary election and April 29 election.

Putnam Partners put together the Ross campaign's running ad -- which showed Ross sprinting through Boston handing out his platform -- and an ad for state Rep. Carl Sciortino's Congressional run to replace Ed Markey. Their past clients include former Mayor Thomas Menino, former US Rep. Barney Frank and New York Gov. Andrew Cuomo. Current clients include Warren Tolman's campaign for state attorney general, Alison Lundergan Grimes' campaign for US Senate in Kentucky and U.S. Sen. Mary Landrieu of Louisiana.
