In Online Political Ads, Facebook Is Catching Up to Google

Facebook's share of online political advertising dollars is quickly growing to rival Google's, online political consultants say.

The ratio of dollars spent directly on Google advertising to those spent on Facebook advertising could be roughly three to two -- even though Google has been around as a political advertising medium for nearly twice as long. The data is only on do-it-yourselfers, omits the spending from the most recent round of primaries, and also does not include the millions of dollars that have already been spent on online ads that were bought this year through consultants, but those same consultants say that the data is in line with their own observations.
