Reps. Edward J. Markey and Stephen F. Lynch resumed their Senate special-election campaigns on Monday. It’s been one week since the two Bay State Democrats suspended political activities after the Boston Marathon bombing.

Markey’s spokesman confirmed via email that he will start campaigning again, although neither candidate is running television ads yet:

The two Democrats will compete in a primary just more than a week away, on April 30. A new poll released Monday showed Markey leading Lynch, 44 percent to 34 percent, in the Democratic primary. Every public survey has shown Markey leading the field.

All of the candidates, Democrats and Republicans, had an uneasy transition back to politics in the wake of the bombing. On April 19, law enforcement authorities captured bombing suspect Dzhokhar Tsarnaev after a city-wide lockdown and a manhunt.

The winner of the Democratic primary is expected to win the Senate special election on June 25. Secretary of State John Kerry resigned from the Senate to join the president’s Cabinet earlier this year, prompting the contest.
