Via John Battelle, Google for President from Slate is another take on the idea that political candidates should be making use of search advertising. But some other articles have been better, in that they include comments from some actual campaigns. For a roundup of those, see Candidates Missing Out On Search Ads. I've still yet to see anyone actually talk directly with the Bush and Kerry campaigns themselves, however.
Well, if the US presidential candidates won't come to the search engines, the search engines will come to them. At least Yahoo to former Democratic contender Howard Dean, that is. He's now shilling (and yelling) for Yahoo Local. Check out the radio spot via the Yahoo Search Blog: Howard Dean on Yahoo! Local.
