Interesting. I'll agree that this points to the organization having a preference in the outcome here.

However, the original post that started this thread seemed to indicate that their data was suspect due to their bias. I remain very skeptical of this, given that their goal is to collect all the political ads and speeches, regardless of party or candidate. Time will tell I guess, but until we have indications otherwise I will continue to consider the Internet Archive's library a reliable source of unbiased information.
