Get your red-hot presidential ringtones!; customize your very own Obamalogo at Logobama; send a video message directly to one of the campaigns; track Clinton's new web-based fundraising push; and find out which candidate is most popular on Twitter.

Warning: visiting the front page of Amigos de Obama will cause an enthusiastic reggaeton paean in Spanglish to Barack Obama to start playing and offer you no way to stop it. Which is why I recommend you skip right to the about page, which contains the lyrics (excerpted below) and explains how the words came to the (anonymous?) author in February after having been inspired by the candidate's "authentic" message. Gosh, where do you think he picked up that talking point?

Anyway, the interesting tech angle is that you can also download an MP3 or put the ringtone on your phone.
