For a completely contrasting style, there's Republican front-runner Donald Trump.
He doesn't have a mobile app. And an autopsy of Trump's website shows that, aside from very basic Google and Facebook tools, there's no tracking technology running under the surface. Trump, in building a 261-delegate lead over Cruz, including victories on Tuesday in Florida and Illinois, has energized his voters via his almost 7 million Twitter followers (Cruz and Ohio Gov. John Kasich have less than 1 million) and a slightly lesser number of Facebook fans.
He also, of course, benefits from constant TV appearances, whether at his raucous rallies or on the interview circuit. According to an analysis published by the New York Times, with data from mediaQuant and SMG Delta, the real estate developer has generated more than double the so-called earned media time as Clinton, six times as much as Cruz and 50 times more than Kasich.
Where this strategy will be greatly tested is in the general election, should Trump win the nomination.
Dheeraj Pandey, CEO of cloud data center and storage vendor Nutanix, said that Trump has a strong front office in generating leads and excitement through social media and rallies, but his limited data collection and resource planning could create a problem.
Winning against the analytics-driven machine the Democrats have put together will require finding exactly where the most important swing-state independents are and sending them targeted, timely messages.
"It's about getting everyone to come and vote on election day, and there big data is really important," said Pandey. "If your back office is weak, all this chest-thumping goes nowhere."
As influential as technology is in the campaigns, Silicon Valley has been noticeably absent from the political debates. Other than every candidate being faced with the inevitable question of whether Apple should be forced to help the FBI crack an iPhone tied to the terror attack in San Bernardino, California, the hot topics in tech have hardly been broached.
