The Republican presidential candidates and their supportive super PACs have spent more than $87 million on television advertising since the beginning of the race, according to figures compiled by GOP sources watching the ad buys.
More than half that total -- $50 million -- has been spent on Mitt Romney's behalf. Romney's campaign has dropped $16.7 million on television ads, while the pro-Romney Restore Our Future has spent nearly $33.3 million pounding away at Romney's rivals, the figures show.
Romney's allies have outspent his rivals in every state that has held contests so far. This week alone, Romney is spending $540,000 in Wisconsin, while Restore Our Future is up with a total of $2.2 million in advertising spread over seven states with upcoming contests.
