“Given Erin’s support of the post office and her continual advocacy on issues that directly involve the working class and the survival of the post office, we wholeheartedly endorse Erin. There’s no other choice. The post office employs the most veterans of any private or governmental employer, and our service to the nation is unequivocally linked to Erin and her support of us. Erin’s proven support of labor is one of the reasons why Branch 111 National Association of Letter Carriers have chosen to support Erin Mendenhall.”
