Both Ask Jeeves and Google have special logos for Election Day 2004 in the U.S.
Clicking the Ask Jeeves logo searches for the word "vote" and offers you an Ask Jeeves "Smart Search" box filled with direct links to polling place info, poll numbers, and much more. Nicely done.
Yahoo doesn't have a special logo today. However, they do offer a box on the Yahoo.com home page with direct links to polling place info, candidate info, endorsements, and more.
