Pro-Romney Super PAC launches new ad wave

Restore Our Future, the Super PAC backing Republican presidential candidate Mitt Romney, will launch a $7.6 million television ad sweep across nine states, its latest contribution to the growing media presence of outside spending groups in the US election.

The ads will run through the end of June in presidential battleground states of Colorado, Florida, Iowa, Nevada, New Hampshire, North Carolina, Ohio, Pennsylvania and Virginia. The Super PAC backing President Barack Obama's re-election, Priorities USA, has been on air in five of those states since late May with $7 million worth of ads that hit Romney over his tenure at a private equity firm.
