“They’re obsessed with the dog thing,” liberal journalist Chris Hayes said on his MSNBC program Sunday morning, referring to the Obama campaign. “And the reason is that, I have heard, in focus groups, the dog story totally tanks Mitt Romney’s approval rating.”

That is what happens when a presidential campaign raises hundreds of millions of dollars: It has enough money to convene focus groups to ponder how Mitt Romney treated his dog decades ago…

Meanwhile, politically savvy liberals outside the White House are worried that many, perhaps most, Democrats aren’t taking Romney seriously, either. “I wonder the degree to which Democrats and liberals and progressives are underestimating the formidable nature of the Romney campaign,” MSNBC’s Hayes asked Bloomberg View columnist Jonathan Alter on Sunday.

“Totally underestimating,” Alter replied. “I run into people all the time who say, ‘Obama’s got this.’ They don’t know what they’re talking about.”
