Democratic Sen. Sheldon Whitehouse of Rhode Island recently spoke with Business Insider while promoting his newly released book, "Captured: The Corporate Infiltration of American Democracy."

Whitehouse is a fierce critic of the role that money plays in politics in a post-Citizens United America.

Elected in 2006, Whitehouse is the ranking member of a Senate Judiciary subcommittee investigating Russia's role in the 2016 election.

Business Insider discussed a number of topics with Whitehouse, including the lessons learned from President Donald Trump's election, what the Democrats must sell to voters to win in 2018 and 2020, and the continually evolving role of money in politics.

This interview has been edited for clarity.

Allan Smith: How has corporate influence harmed the Democratic Party specifically?

Sheldon Whitehouse: It rather specifically kept us from getting a majority in the Senate in this election because the Koch political operative group, Americans for Prosperity, had pledged to spend $750 million, and they didn't really like Trump. They didn't get behind him in a big way. So a lot of that money instead went into general fieldwork. They had, for instance, 14 field offices in Florida. Just ready to help whomever. And that stayed in place when Trump became the candidate. They weren't going to go anywhere else. But they couldn't and didn't spend at all in the presidential. So they turned to the swing states, and they spent immense amounts of money in Wisconsin, Ohio, and Pennsylvania.

They spent something like $40 million beating the crap out of the governor [Ted Strickland], so he never really got off the ground. He was just so badly strafed as he pulled his candidacy out onto the runway that Rob Portman, who was behind him in the early polling, ended up winning by a huge margin. Basically, people had given up on the race by then it was so catastrophic. They turned Ron Johnson from a 12-, 15-point underdog into a narrow, real victory. They edged out Katie McGinty in Pennsylvania. And I think each one of those states was in the $20 million to $40 million expenditure range. So that's a pretty big deal.

Smith: Do you think that played a role in Trump's victories in those states? Maybe those senators picked him up a bit.

Whitehouse: Yeah, I think that when you've got a largely zero-sum electorate, as there's largely Republican and Democrat and not much else. When you can get out your leaning-Republican vote, if you can get them out for Ron Johnson in Wisconsin, once they get in, they're probably going to be more likely to vote for Trump. So I think the waves kind of built on each other, even if Koch people weren't all that excited about Trump personally, but besides their operation in Florida undoubtedly helped Trump down there. And in addition to our Senate candidate getting defeated there as well. That's a pretty obvious way.
