Pressley has not officially entered the race or clearly indicated that she intends to do so. But she is reportedly considering a run and quietly speaking to allies about the possibility. Pressley, 51, could make a similar age-related argument as Moulton. She is also one of the most notable progressives in the House of Representatives, and could eat away at Markey's more left-leaning base of support. The poll results released this week could further embolden her.
