The Republicans have done a much better job of using search to reach voters. Former
Massachusetts Governor Mitt Romney, former New York City Mayor Rudy Giuliani (who hasn't even formally announced his candidacy), Sen. John McCain (R-AZ), and Rep. Tom Tancredo (R-CO) are buying
keywords.
The Republicans are even buying competitors' keywords. Of the Democrats, just Bill Richardson, the Governor of New Mexico, and Tom Vilsack, the former Governor of Iowa, are
using search marketing; surprisingly, Sen. Hillary Clinton (D-NY), Sen.Barack Obama (D-IL), and former North Carolina Sen. John Edwards have not.
