A top adviser to Newton Mayor Setti Warren is looking for young people with campaigns under their belt to potentially staff his U.S. Senate bid. In an email seeking help earlier this month, obtained by the Reporter, political consultant Deborah Shah wrote that she may be staffing up at the end of April for the potential Senate campaign.

Pay may be “limited,” she wrote, but “top performers” will have a shot at staff jobs starting over the summer or right after Labor Day in September.

Warren, who was in Dorchester this week for President Obama’s visit to TechBoston Academy, has told reporters he is weighing a challenge to U.S. Sen. Scott Brown (R-Wrentham), and he is expected to make a decision sometime in the spring.

Shah told the Reporter Saturday that a decision will be made in the next month or two. She said she was reaching out to students who are graduating to give them an opportunity to hop on board a potential campaign.

“This is just the first step to make sure you’re prepared” in case Warren runs, she said.

A former aide to U.S. Sen. John Kerry and an Iraq War veteran, Warren was elected Newton mayor in November 2009.
