Obama proves a tough challenge in the online general election season for likely Republican nominee Mitt Romney. Obama spends 2x as much on Google Advertising, has 8x more Facebook likes, and 5x more Twitter followers than all the Republican candidates combined. Mitt Romney has done the best job of the Republican candidates in controlling his online message; his official website appears on page one of the search results for online searches about him almost half the time, more often than the other candidates, and he has several times the Facebook ‘Likes’ of the other candidates. Although Rick Santorum recently dropped out of the race, he provoked more Google searches (51% more searches than Romney, and 79% more than Gingrich) and received the largest share of online news coverage in March at 35%.
