Rob Delaney won't stop picking on Mitt Romney, and it's making his career. The comedian's tweets about the Republican nominee are so popular they're routinely in the top three mentions of Romney on the social network. 

Mitt Romney's been trying to up his social media game lately. At just under 800,000 Twitter followers, he's getting dwarfed by the President's 18 million. His numbers have been going up despite statistics that say his following is inflated. It can be hard out there for a Presidential candidate in the social media landscape, though. Someone might make fun of you. Even worse, they might be so good at making fun of you they get a profile in Bloomberg Businessweek by Joshua Green, formerly of The Atlantic, that calls you, "Mitt Romney's Twitter Nemesis." Enter Delaney, whose tweets about Romney are so great they're routinely in the top three most popular mentions of Mitt on any given day. Green writes:

At Bloomberg Businessweek’s request, VoterTide, a social media analytics company, measured Twitter mentions of Romney in June and found that Delaney’s were the most popular 44 percent of the time. On days when the real Romney took the top spot, Delaney was often second. And third. “Much of the time, his followers are pushing his message further and connecting with people better than Romney himself is doing,” says VoterTide’s co-founder, Jimmy Winter.

Despite all of Delaney's spotlight stealing, the two men have nearly identical Klout scores. Delaney has over 500,000 followers himself, and his tweets about Romney usually get plenty of retweets and favorites. In terms of the greater scheme of the election, Delaney sees himself on the same level as something like Restore Our Future. "To the extent I can wield Twitter influence, I prefer to function like a much cleaner, more honest super PAC," he told Green, who is no stranger to Twitter himself. Delaney told him he tried to quit making fun of Romney a few months ago, but he couldn't resist. "It’s like an addiction."
