Lisa Rea sums up the biggest challenge for all three candidates hoping to unseat Doolittle:
Moving into the November election, Rea said it would take between $500,000 and $1 million to match up with Doolittle from a money standpoint.
"This is part of the problem," Rea said. "None of his challengers can come close to the amount of money he raises."
Doolittle's focus on fund-raising and forming relationships with lobbyists who in turn promote clients to donate to Doolittle is a problem that needs to be addressed in the election and in Congress, Rea said.
