Rep. John Delaney (D-Md.) filed for reelection Tuesday, a move likely to end speculation that he could run for governor.

There had been chatter for more than a month about the first-term congressman from Montgomery County making a late entry into the Democratic field, fueled in part by a telephone poll that included Delaney’s name as an option for governor. Delaney declined to say at the time whether it was his poll. In a statement late last month, he did not categorically rule out the possibility of seeking the governor’s office.

Delaney was spotted at the State Board of Elections office in Annapolis filing to run again for his 6th District seat. He did not immediately return a phone call seeking comment about the decision.

A Washington Post poll released Tuesday shows that Delaney would have started a statewide race without much of a following. Among Democrats, 16 percent said they have a favorable impression of Delaney, while 9 percent said they have an unfavorable impression. Seventy-five percent have no opinion.

Asked about the current candidates, 34 percent of Democratic and Democratic-leaning independent voters support Lt. Gov. Anthony G. Brown in the primary, while 15 percent back state Attorney General Douglas F. Gansler and 8 percent support Del. Heather R. Mizeur (D-Montgomery). Both Gansler and Mizeur, like Delaney, are from Montgomery County.

In theory, Delaney could still switch races, but that now seems highly unlikely. The filing deadline is Feb. 25 at 9 p.m..
