(CNN) - Democrats kept their eye on GOP hopeful Mitt Romney Sunday, singling out the Republican frontrunner for his record at a private investment firm and providing further evidence Democrats see the former Massachusetts governor as the strongest candidate in the Republican field.
Rep. Debbie Wasserman Schultz, chairwoman of the Democratic National Committee, took Romney to task for what she said was an inconsistent record while defending her organization's relentless stream of anti-Romney videos and memos, saying the candidate deserved the onslaught.

"Mitt Romney is one of the candidates who is near the top or at top of their field, and he's invited and deserves that scrutiny because he has been distorting and mischaracterizing the presidents record," Wasserman Schultz said.
She continued, "Mitt Romney has no conviction, has flip-flopped on every issue, and voters need to know."
The DNC has kept almost singular focus on Romney over the past several months, producing a series of web videos that call into question Romney's consistency on issues and his role at Bain Capital, the private investment firm he founded in the 1980s.
Romney's campaign has characterized the attacks as distractions from President Barack Obama's record on job creation and economic growth.
On Sunday, Wasserman Schultz flatly rejected the suggestion by Fox News Host Chris Wallace that Romney's tenure at Bain Capital was comparable to President Barack Obama's role in the failed energy firm Solyndra, saying the assessment was "apples and oranges."
The federal government offered half a billion dollars in loan guarantees to Solyndra before the company went bankrupt in 2011. Wallace compared the lay-offs that took place after the company's bankruptcy to lay-offs at companies acquired by Bain Capital.
"The decisions that were made at Solyndra that ultimately led to their bankruptcy were those of people who worked at Solyndra," Wasserman Schultz said.
On ABC's "This Week," top Obama adviser David Axelrod took similar aim at Romney, saying his record at Bain Capital signaled an anti-worker mindset.
"I don't think that, frankly, bringing a Bain mentality to this economy, to running this economy makes him a strong candidate," Axelrod said. "I don't think shifting and moving around on positions, fundamental positions is one that people are going to embrace. Trust is a big issue in the presidency. I think there's a big trust question when it comes to Governor Romney."
At Saturday's GOP presidential debate, Romney said his record of creating jobs at Bain was strong.
"In the business I had, we invested in over 100 different businesses, and net-net, taking out the ones where we lost jobs and those that we added, those businesses have now added over 100,000 jobs," Romney said.
Axelrod said Romney's claims about job creation at Bain didn't ring true.
"I know he says it's a net-net number, and he said I'm a numbers guy. The problem is that neither he nor his campaign can furnish any evidence to support that," Axelrod said.
Axelrod continued, "He's not a job creator, he's a corporate raider. Those aren't the values that we want to lead our economy."
