At the annual White House Correspondents’ Dinner this weekend, President Obama delivered 20 minutes of his trademark dry humor, working in jabs at Michele Bachmann, Joe Biden, climate change deniers in Congress, and himself, to name a few. Perhaps some of the most pertinent jokes of the evening came about halfway into his speech, when he poked fun at the 2016 GOP presidential field, the Koch brothers and the influence of big money in politics.

“Soon the first presidential contest will take place, and I for one cannot wait to see who the Koch brothers pick,” President Obama joked. “It’s exciting… the winner gets a billion dollar war chest. The runner up gets to be the bachelor on the next season of The Bachelor.”

“I mean, seriously – a billion dollars,” the president continued. “From just two guys. Is it just me or does that feel a little excessive?”

The president making these pointed jokes is the latest example of a growing cultural awareness of the problems stemming from big money in politics. With presidential candidates Hillary Clinton, Sen. Lindsey Graham, and Sen. Bernie Sanders all in support of a constitutional amendment to overturn Supreme Court decisions like Citizens United, this issue is rapidly ripening for broader public discussion.
