Four new ads from Republican presidential hopeful Mitt Romney tailor the candidate’s message for four swing states--Iowa, Ohio, North Carolina and Virginia--promising specific policy achievement during his first 100 days in office.

It’s an expansion of the former Massachusetts governor’s “Day One” ad campaign, in which Romney detailed some of his plans for his first day in office. The ads subtly attacked President Obama’s policies while framing Romney as a politician concerned more with what happens after the election.

The policy ideas in these ads aren’t new, but they offer a window into what Romney thinks will be key issues in some battleground states.

In Iowa, Romney promises to “repeal Obamacare and attack the deficit, starting with $20 billion in savings,” working towards a balanced budget so Iowans can have “fewer worries about their future and their children’s future.”

In Ohio, Romney pledges to demand “a level playing field” from China and repeal “regulations that are strangling our energy industry and costing us jobs,” making the state “a better place to do business as we see more factories and jobs coming back.”

In Virginia, Romney touts plans to reverse “Obama’s offshore drilling ban, creating thousands of new jobs for Virginians.” And in North Carolina he would “cut taxes that kill jobs,” bringing “new certainty to our economy and the promise of new banking and high-tech jobs.”
