On the campaign trail and in two different TV ads, Boxer has relentlessly criticized Fiorina for shipping jobs overseas - and tried to contrast that with her own record in the Senate.
Boxer ad #1: "As the CEO of HP,
Carly Fiorina laid off 30,000 workers…"
Boxer ad #2: "I'm Barbara Boxer and I approve this message because I want to see the words 'Made in America' again!"
So when Fiorina appeared at a suburban Sacramento digital display manufacturer Monday, it wasn't a surprise to see the words "Made in America" as the electronic backdrop. And Fiorina brought the subject up immediately - just 45 seconds in:
Fiorina: "All of us want to see the words Made in America on our products. But unfortunately, Senator Barbara Boxer uses that phrase as a cynical political slogan."
Fiorina says Boxer has voted for higher taxes, increased regulation and bigger government.
Fiorina: "Every single one of the policies she has supported has helped to destroy jobs and, in particular, manufacturing jobs here in the state of California."
But Boxer campaign spokesman Mark Armour says it's Fiorina's record that's out of touch with her remarks.
Armour: "Facts are completely wrong. It's Barbara Boxer who voted to give incentives to small businesses to build products made in America. It's Barbara Boxer who voted to stop companies from shipping our jobs overseas. Ms. Fiorina supports all those policies."
The candidates continue to disagree on taxes and how to help small businesses. On Monday, Fiorina said she wants to extend the Bush-era tax cuts for everyone. Boxer wants to extend them for those making 250-thousand-dollars a year or less. And Boxer voted for a bill aimed at helping small businesses that passed the Senate last week; Fiorina opposes it.
