The Democrats
On the other hand, Democrats running to replace George Bush have not held back when it comes to using TV ads. Bill Richardson leads the pack, airing over 4,000 commercials in an effort to move up in the polls in the early states of Iowa and New Hampshire. Barack Obama is close behind with close to $2 million invested in TV time, mostly in Iowa. Hillary Clinton and John Edwards, because of their profiles, were able to skip the typical bio spots and have spent far less. The Edwards campaign has made relatively small buys in Iowa and New Hampshire, but has also used ad buys tactically on cable TV and in Washington to inject himself into the Iraq war debate. Clinton, on the other hand, has spent over $1 million on TV in just five weeks and her latest buys on South Carolina radio signal the campaign is serious about running the table on the early primaries.
Others on the Democratic side of the ledger have gotten in on the act with the Biden and Dodd campaigns combining for over $1 million dollars in TV ad spending with compelling messages about the war and global warming. As for the Democrats use of web advertising, the Obama campaign leads the way with almost $300,000 in online spending, Clinton and Edwards have also spent on online ads.
