Fiorina deputy campaign manager Julie Soderlund:

"Today Tom Campbell kicked off yet another campaign for yet another office in his never ending quest to get elected again - but using his electoral history as a guide, his kick off tour is more likely to be a farewell tour. Tom's unending quest for statewide office has nothing to do with serving the people of California, rather it's about satisfying Tom Campbell's quixotic personal ambition and the false premise that he will be acceptable to Republican primary voters. California Republicans won't vote for a proponent of higher taxes and more government; they're smarter than Tom Campbell gives them credit for.

"We view Tom's candidacy as an opportunity for Carly to further distinguish herself as a political outsider and fiscal conservative who will always be on the side of the taxpayers - not just for the primary election, but also for the general election. Tom Campbell and Barbara Boxer share many of the same views, not the least of which is their mutual support for increased taxes and government expansion. Running against Tom in the primary provides our campaign an ideal sparring partner for the main event."

Chuck Devore:

"I've known Tom Campbell for many years in public life, and he has my respect as a substantive and well-intentioned participant in California politics. We don't agree on much: he wants to raise taxes, and I think they're too high; he's pro-abortion, and I'm pro-life; he's a moderate-left politician, and I'm a proven conservative leader. But we do agree that a vigorous discussion among Republicans on these matters is overdue. With Tom Campbell in the race, we can finally have that conversation."

DeVore communications director Joshua Trevino:

"The real story in Tom Campbell's jump to the Senatorial race is the ongoing implosion of the Carly Fiorina candidacy. Make no mistake: Campbell would not be a Senate candidate if Fiorina's fundraising was not lackluster, if her establishment backing was not shaky, and if her inevitability narrative was not in tatters."

DeVore campaign manager Leisa Brug Kline:

"Tom Campbell's entry in this race obviously changes the dynamic quite a bit. The race between Chuck DeVore and Carly Fiorina was a contest between a real conservative, and a moderate-left millionaire who desperately wants to be seen as conservative. Campbell brings an unashamed and forthright moderate-left perspective to the race. California Republicans now have a choice between two genuine and differing candidates -- and that's a good thing."
