WASHINGTON — Sen. Ted Cruz, the first major Republican candidate to declare his White House candidacy, raised $2 million during the first three days of his presidential campaign — as his team deployed a mix of complex social-media strategy and behavioral analytics to reach and sway potential donors.
Hours before his announcement speech Monday in Lynchburg, Va., Cruz tweeted the news that he was running for president. That day, he had 5.7 million interactions on Facebook. So far, nearly two-thirds of his fundraising haul has flowed in through the Internet, aided behind the scenes by a team of data scientists who closely monitor social media and digital traffic to determine who’s reading their messages, who’s sharing them and who’s clicking through to his website and taking action.
