Yesterday Senator Obama became the latest U.S. presidential candidate to visit Google headquarters in Mountain View for a talk and then Q&A. We're heartened to see how most every candidate is taking full advantage of the Internet, by making good use of YouTube together with their own websites, blogs and social networks to inform voters of their positions and share more of their thinking than traditional campaigns ever allowed.

The next big event we're looking forward to is the November 28 CNN/YouTube Republican debate. Stay tuned for that, and if you'd like to watch the talks other candidates have given at Google, here they are.
