The Jury Talks Back


Mercury News article on poll misstates Fiorina’s chances

Filed under: California Politics — aunursa @ 7:48 pm

The San Jose Mercury News reported that Carly Fiorina holds a comfortable lead in the race for the Republican nomination to challenge incumbent Senator Barbara Boxer.  However writers Ken McLaughlin and Mike Zapler erroneously concluded from the Los Angeles Times/USC poll that “in a theoretical matchup, only one of the three GOP primary candidates can beat [Boxer]: former Silicon Valley congressman Tom Campbell.”

How do they draw that conclusion? By determining that moderates swing elections in California.  “Among the moderates, Campbell, a fiscal conservative who supports abortion rights and gay marriage, beats Boxer 46 percent to 33 percent. But Boxer beats Fiorina among moderates 48 percent to 30 percent.”  The photo caption emphasized, “Carly Fiorina will likely win the GOP candidacy for the U.S. Senate but will not unseat Democrat Barbara Boxer.” [emphasis added]

Based on that poll, Fiorina’s chances would indeed be slim if moderates and only moderates voted.  But even McLaughlin and Zapler acknowledged that 31% of registered voters identified as conservative and 24% identified as liberal in addition to the 39% that identified as moderate.

Therefore the relevant question is not which candidate would moderate voters prefer, but which candidate would the be choice among all registered voters.  So who wins in a Boxer-Fiorina matchup among registered voters?  Amazingly, the writers didn’t even mention the poll result in the article.  To get the answer I had to find the actual poll.  Reviewing the data, I discovered that Boxer’s lead over Fiorina is just 44-38 among all registered voters (including leaners).  While that’s more favorable to Boxer than a race against Campbell in which he leads 45-38, a mere 6 point margin with over five months left is much too close to count out Fiorina.  (Among likely voters, Boxer hold a similar 45-39 lead over Fiorina.)

I would be interested to know whether writers took into consideration the enthusiasm gap when considering likely voters.  There’s a good chance that pollsters are underestimating the significance of conservative and center-right voters to sway the election.   At any rate, the Mercury News made a sloppy error in failing to consider — or even report — the full poll result.


  1. although i think DeVore is the best of all the candidates, i can be persuaded to hold my nose and vote for Carly in November. there is no way in hell i’m voting for Campbell for anything.

    this is just another case of the MFM trying to influence elections under the guise of “reporting”.

  2. redc1c4, I had thought the same thing but decided, not this time – Devore is by far the best of the three and he’s earned my vote.

    I’m tired of polls and numbers deciding for me and I end up giving my vote away like a cheap whore. No more. It’s the best candidate. Let the chips fall where they will.

    After all, how much worse can Cali get? If anyone of the three get in, it will still be a thousand times better than what it’s been, so why not vote for the best man or woman for the job?

  4. The story reeks of template journalism: But “bases” don’t swing general elections in California. Moderates do.

    I’ll be kind and suggest the reporters were just lazy, and stopped reading the poll once they found the numbers that fit the template.

  5. I voted for Fiornia and pretty much the only reason I picked her was I think she’s the one — not Campbell — who has the best chance of beating Boxer.

    Here’s what the Campbell boosters miss — their guy can’t raise money for jack — he was forced to go dark for the last week before the Primary. A Republican candidate who can’t raise money is DEAD in California. The RSCC will not going to bail out Campbell; the amount of $$ needed to do so would be much better spent, in their mind, on multiple races in less expensive districts. Fiornia has her own problems but she can match Boxer’s $20 million war chest, and then some. Campbell can’t, therefore he can’t win.
