How far down the Rubicon they have gone

This one was heard on the talk radio program, the “Clay Travis and Buck Sexton Show”. They were discussing how some political commentators are starting to speak histrionically as we approach the upcoming election. This is a mashup of “down the rabbit hole” (in a situation or journey that is particularly problematic or chaotic) and “crossing the Rubicon” (passing a point of no return). The Rubicon is a river in Italy so one can very well go “down” it, but Julius Caesar crossing it in 49 BC precipitated Caesar’s Civil War. A big thank you to Verbatim for hearing this one and sending it in!
