According to Google Trends, Barack Obama has been the subject of more Google searches than any other presidential candidate, and aside from Ron Paul and Mike Huckabee he blows everyone else out of the water.

This view from Google Trends shows that, when compared with Hillary Clinton, John Edwards, Mitt Romney, and Rudy Giuliani (you can only compare five candidates at a time), all of whom experienced a bump in searches following the Iowa caucuses, there were many times more searches for Barack Obama than for any other candidate.

When Mike Huckabee is thrown into the mix (replacing Mitt Romney in our case) things change a bit, but he still was not searched for nearly has much as Obama. The same goes for Ron Paul, for whom the supporters’ slogan of “Google Ron Paul” seems to be working.

Matt Tatham of Hitwise also reports that searches for "barack obama" increased 506% to make it the fastest moving search term last week.

Clearly, there's a ton of attention being paid to Obama right now, online and off. Voters that hadn't heard of him or are only now taking his candidacy seriously are flocking online and using the trusty Goog to find out who this guy is. And they're going to YouTube to get a more in-depth picture.

In fact, a lot of them are going there.

This chart from our data-crunching buddies at TubeMogul shows that since the Iowa caucus on Jan. 3rd, there have been almost 1.5 million people views of Obama's videos on YouTube. That's more than 16% of his total video views. Ever. Remember, video counts are only recorded if people watch the whole video, so the number of people actually checking out his videos could be much higher. Also, the newer, more popular videos aren't 30-second ads, they're minutes-long slow burners. Folks are taking the time to watch this stuff.

The most popular video of the last week has been Obama's Iowa victory speech:

The speech was broadcast live on national TV and repeated over and over again, so it may have combined with the Iowa results to convince a lot of skeptics or those not paying attention that this guy is for real, and that (white) people are supporting him. It's now been viewed on YouTube over 586,000 times.
The video Barack Obama's Road to Change is a primer on Obama's message and his travels through New Hampshire, made to look as rosy and down-home as possible.

The video provides the kind of compelling narrative -- that as Barack traveled through New Hampshire this summer he inspired people with talk of change -- that can help educate interested voters. This one's been viewed more than 84,000 times.
