Elizabeth Warren is already focused on unseating Republican Sen. Scott Brown in the Massachusetts Senate race, but first, she'll have to get through the Democratic primary in September.

Five of her would-be challengers have already give up, but two -- Marisa DeFranco and Jim King -- are still in the running.

As WBUR reports, they're a little frustrated that Warren hasn't joined them in candidate forums throughout the state.

"We’d love to have Elizabeth Warren here and in other forums in the future," King said at one event. "We can articulate our individual positions on the issues that are important in this campaign."

Warren, meanwhile, has been extraordinarily successful in fundraising, and was leading Brown in a December poll.
