In prior articles, we found the scientific validation of Stephen Colbert's 'truthiness', and now it turns out that anecdotal evidence of a 'Colbert bump' following an appearance (anecdotal evidence provided, naturally, by Colbert himself) on the show has legs as well - but only if you're in one political party. Democratic politicians receive a 40% increase in contributions in the 30 days after appearing on "The Colbert Report" while Republicans essentially gained nothing.

Stephen Colbert is right - the "Colbert bump" boosts campaigns.

This analysis of one of America's most well-known pop icons of recent years is conducted by political scientist James H. Fowler (University of California, San Diego), who is also a self-identified fan of the show. The research appears in the July issue of PS: Political Science and Politics.

While Fowler notes that Colbert often makes "outlandish" claims for laughs, he also observes that specific segments of the program are devoted to politicians and that politicians themselves have taken notice of the Colbert Report's impact. Moreover, even a cursory analysis demonstrates that despite being a comedy program "The Colbert Report" appears to exercise "disproportionate real world influence", likely due to the "elite demographic" of its audience.

To investigate the claim of the Colbert bump, the author uses data acquired from the Federal Election Commission on fundraising by Congressional Democrats and Republicans. His analysis finds that Democrats who appear on "The Colbert Report" enjoy a significant increase in the number and total amount of donations they receive over the next 30?? days when compared to similar candidates who do not appear on the show.

Specifically, Democrats who come on the program raise $8,247 more than colleagues who don't do so on the 32nd day following their appearance—"a bump of roughly two-fifths over the normal rate of receipts." Republicans do not appear to benefit at all from appearing on the program; notably, they raise more funds in the month before coming on the program while actually raising less money in the month following their appearance—hinting at a possible "Colbert bust" for the GOP instead.

While conceding that it is "important not to read too much into these results" Fowler does also state that "one might be tempted to dismiss the importance of the Colbert bump because it is just money." Clearly, political fundraising is done for a purpose and the most important consequence of any bump is whether Colbert candidates win elections. With only the 2006 elections having been completed since The Colbert Report came on the air, the upcoming 2008 elections will likely provide greater insight into this interesting and humorous wrinkle in modern American politics.
