Romney’s spending far exceeds that of his nearest Republican competitor, John McCain, who has spent over $300,000 on campaign ads.  On the Democratic side, Barack Obama leads the way, having spent $3.9 million on television commercials.  Tied for second are Hillary Clinton and New Mexico Governor Bill Richardson, each of whom have spent $2.2 million.

Romney’s strategy is one that hasn’t necessarily paid off in the largely undecided Republican race. 

Rudy Giuliani, for instance, has chosen not to air TV commercials, says CNN. In its coverage, CNN quotes Stuart Rothenberg, editor of the Rothenberg Political Report as saying, “Giuliani apparently has decided to hold his fire until Florida at the end of the month and then February 5, which explains why he hasn't begun a TV campaign.  It is a risky strategy given Romney's efforts to sweep the early contests. But it could pay off if -- after the South Carolina primary -- the GOP race is fractured."
