RandPaulWith many months still to go in the 2016 presidential election season, campaigns keep running into problems when it comes to mixing their political messages with music. 

The latest incident involves the campaign of Sen. Rand Paul (R-Ky.), which uses a video criticizing Sen. Marco Rubio (R-Fla.) for missing Senate votes. The video employs the theme song to the “Where in the World Is Carmen Sandiego” educational computer game series, and The Hollywood Reporter reports that the copyright holder was not happy. 

Donald Trump’s campaign recently posted a video of a trio of girls singing a pro-Trump song to the tune of the World War I patriotic ditty “Over There,” and there were reports that EMI Music requested takedowns more than once. 

This isn’t the first time that the race for the Republican presidential nomination has prompted objections from holders of copyrights in musical works. 

Back in the fall, Aerosmith’s Steven Tyler objected—apparently temporarily—to Trump’s use of “Dream On” during his campaign.

And Mike Huckabee drew barbs from Survivor guitarist Frankie Sullivan for using the song “Eye of the Tiger” without the band’s permission in connection with his appearance at a rally for Kim Davis, the Rowan County, Kentucky, clerk who was jailed for refusing to issue marriage licenses to same-sex couples.
