Marco Rubio Leads Presidential Hopefuls When It Comes To Silicon Valley Fund Raising

The tech industry may be known for leaning blue, but in the 2016 election cycle, presidential hopeful Marco Rubio has already tapped deeply into Silicon Valley's extensive wealth, raising more funds than any other Republican.

At $3.03 million, the Florida senator has almost six times as much tech money as any other presidential hopeful, according to to Re/code, citing information from Crowdpac, a nonpartisan startup that tracks political data. That's quite the lead, but Rubio has quite a ways to go before locking down the tech industry. Of Rubio's tech funds, $3 million have come from just one man: Oracle Chairman Larry Ellison, who is known for contributing to members of both the Republican and Democratic parties.

The rest of Rubio's tech donations have been significantly smaller four-figure amounts from a few tech individuals, including Oracle CEO Safra Catz, Seagate CEO Steve Luzco and Cisco Systems Chairman John Chambers. Surprisingly, Rubio also landed a 2013 $2,600 contribution from Facebook CEO Mark Zuckerberg, who did not donate any money during the 2012 election.

After Rubio comes Republican Jeb Bush, who has raised $525,000 in tech donations, Democrat Hillary Clinton with $247,000, independent-running-as-Democrat Bernie Sanders with $134,000 and Republican Chris Christie with $100,000. All other presidential candidates have raised less than $100,00 from the tech industry, which appears to be biding its time before rallying behind any particular candidate.

Clinton is the only candidate to have received donations from many key tech players, including Facebook COO Sheryl Sandberg, Tesla and SpaceX CEO Elon Musk, Dropbox CEO Drew Houston, YouTube CEO Susan Wojcicki and Craiglist founder Craig Newmark among her donors. Most of those donations, though, have been small, four-figure contributions.

This election cycle it is expected that presidential hopefuls will need to spend at least $5 billion campaigning for the White House. That means that whoever wins will need help from the deep pockets in Silicon Valley.
