UPDATE: The Romney campaign sent over this statement in response to the ad:

“President Obama has failed to create a single net new job and has wreaked more havoc on the middle class than any president in modern history. The last thing the White House wants is to have to run against Mitt Romney and be held accountable for the many failures of this Administration. So, instead of focusing on the economy and creating jobs, President Obama and Democrats are focused on tearing down Mitt Romney.” – Andrea Saul, Romney Spokesperson

The Democratic National Committee will begin flooding the airwaves Monday with a 30-second ad about Mitt Romney, who unveiled his first television ad in New Hampshire last week.

Airing in five battleground states — New Mexico, Pennsylvania, Wisconsin, North Carolina, Ohio — and Washington, D.C., the ad is the Democrat’s latest attempt to paint Romney as a flip-flopper on abortion and on health care.

ANALYSIS: The biggest and most oft-repeated knock on Romney is that he has changed his mind on several issues, and it’s a criticism that has come from Republicans and Democrats. In fact, Romney’s rival Republicans have often articulated the problem more strongly than Democrats, saying that Romney lacks a core (Jon Huntsman) and that he can’t be trusted on key issues that are important to conservatives (Rick Santorum).

And Romney gave Democrats some fodder in their campaign to cast him as someone who makes decisions based on political expediency — the line from this ad, “I’m running for office for Pete’s sake,” comes from Romney at an October debate when he was explaining his approach to dealing with illegal immigrants who were working on his property.

In focusing on the issue of abortion, Democrats are aiming to portray Romney as not only an indecisive flip-flopper, but as someone who might roll back abortion rights, a position that could harm Romney with women voters and among independents. Romney has had to address his position on health care repeatedly in debates and maintains that health care is up to the states, a nuance that this ad overlooks.

Yet Romney has not come up with a strong and consistent response to the overall charge that he has changed his mind, instead choosing to focus on the economy and his business acumen.
