Mr. President, we have to give bears the right to vote... or bears will rise up and then bears will be in congress and we will be the ones performing in the circus, wearing little hats.

Our reading
An editorial interpretation.
An absurd political warning: give bears voting rights now, or they will rise up, take seats in congress, and reverse roles so humans end up performing in circuses in little hats. The humour comes from treating an outlandish scenario as a serious matter of policy prevention and humiliation.
