“Congressman Markey has been a strong and effective advocate for public education and the rights of working men and women,” said Massachusetts Teachers Association President Paul Toner in a release.
Lynch has launched a bid for the Democratic nomination for Secretary of State John Kerry's (D) seat, but he enters the race an underdog.
The former union worker and advocate is relying on heavy, active union backing to help him get out the vote and shore up the deficit in funding he's likely to face against establishment-backed and deep-pocketed Markey.
By his own count, Lynch has secured the endorsements of over local 30 unions in Massachusetts. But his controversial vote against President Obama's health care law in 2010, as well as his more conservative positions on some social issues — like his position in opposition to abortion rights — remain contentious in union circles.
His failure to secure the endorsements of the MTA and the National Education Association indicate he does not have union support entirely locked up, which could become an issue for him as the race heats up and he is forced to grapple with his underdog status.
