Massachusetts Attorney General Martha Coakley is stepping away from the campaign trail for a D.C. fundraiser with Washington Democrats next Tuesday, a week before the Senate special election.

It’s another sign the party establishment is stepping up its support to help push Coakley over the finish line on Jan. 19 — the invitation for the event is circulating around D.C. the same day the family of the late Sen. Edward Kennedy is slated to announce their backing of his would-be Democratic successor.

The whole Massachusetts delegation, including Sen. John Kerry (D-Mass.) and the state’s 10 Democratic House members, are headlining the Jan. 12 fundraiser at Sonoma Wine Bar on Capitol Hill, hosted by Kerry 2004 presidential campaign manager Mary Beth Cahill and deputy campaign manager Steve Elmendorf, lobbyists Heather and Tony Podesta and others.

Hosts are asked to raise $10,000, co-hosts $5,000 and guests are asked for a $1,000 check.
