Sens. Cory Booker (D-N.J.) and Mitch McConnell (R-Ky.) share at least one thing: campaign donors.

Booker, a Senate newbie, and McConnell, the Senate minority leader, show up dipping into the same donor pool more than any other opposing-party members of Congress. They shared 74 donors in the first year of this election cycle.

This comes from a fascinating data dive from the Center for Responsive Politics that broke down which politicians have donor overlap. As the CRP points out, just shy of two-tenths of one percent of American adults donated to campaigns so far this year, so the pickings are slim.

Cashing checks makes strange bedfellows — a politician isn’t going to care who else’s bed a donor has slept in (figuratively, of course).

As the chart below shows, Booker also shares donors with other top Republicans: House Majority Leader Eric Cantor (Va.) and Sen. John Cornyn (Tex.), the Senate minority whip.

And McConnell has donors in common with other Democrats, including Sens. Mark Warner (Va.) and Kay Hagan (N.C.).

Less surprising, politicians from the same party share donors at a higher rate. McConnell also tops that list, with 415 of his donors also contributing to Cornyn. Another obvious duo is Hagan and Sen. Jeanne Shaheen (D-N.H.), who are both running in high-profile, competitive reelection campaigns this year. They share 387 donors.

We’re curious too who these deep-pocketed party hoppers are. Our friends at the CRP are digging up that data (they’re really the best) so we’ll share when we have it.

UPDATE: Predictably, the list of Booker and McConnell crossover donors includes powerful names at Fortune 500 companies, like  Lawrence J. Salva, senior vice president of Comcast, William Lauder, chairman of Estée Lauder Companies, and Eric Schmidt, executive chairman of Google.
