More than $23 million has been spent on campaign television ads so far in the 2012 election with the conservative-aligned outside group American Crossroads accounting for nearly half of that total, according to an analysis of data by the Washington Post.

The spending by Crossroads dwarfs that of any other interest group or party committee active in the 2012 election. The Democratic National Committee places a distant second with $5.2 million; Americans for Prosperity, the tea party-aligned group affiliated with the wealthy Koch brothers, has spent $3 million on ads so far in the election.

Spending by the Republican presidential field lags well behind. As of Nov. 20, none of the Republican presidential candidates had spent $1 million on ads with Texas Rep. Ron Paul ($900,000) and Texas Gov. Rick Perry ($800,000) leading the way.
