a plague on both your/their houses

Said as an exclamation of exasperation with, disgust for, or rejection of both of two opposing people or groups. A line from Shakespeare's Romeo and Juliet, it is used especially in reference to politics. Honestly, I look at the candidates vying for election, both of whom I know will usher in the same status quo as we've had for decades, and I just feel like saying, "A plague on both your houses!" Look, I don't favor one side over the other in this debacle—a plague on both their houses, as far as I'm concerned, because they're both equally responsible. I think that, deep down, they're both sleazy con men, so I'm not supporting either of them. A plague on both their houses!
