Republican presidential candidates ramp up Iowa ads before caucus
Newt Gingrich fought back Tuesday against rival Mitt Romney and negative advertising as the Republican presidential candidates flooded the airwaves in Iowa, with much of their messaging aimed against the former House speaker.
The contenders and their supporters spent almost $1 million on ads in the state last week, more than triple the amount shelled out three weeks ago.
Gingrich acknowledged that the ads against him are working, with new polling data this week showing that his advantage over Romney and status as front-runner have largely disappeared.
With two weeks to go before the crucial Iowa caucuses, Gingrich tried to force a backlash against Romney and the negative ads sponsored by an independent PAC supporting the former Massachusetts governor. Gingrich called on Romney to state publicly that the “super PAC,” known as Restore Our Future, should stop running the attack ads.
