Absolutely, it's a basic technique of information warfare. One variation on this is to undermine a political consensus by creating false support for it that appears enthusiastic but depends partially on fallacies.
For example, suppose you run a baseball team engaged in psychological warfare with another baseball team. You are so evenly matched that it is impossible for either of you to win other than by having the loudest cheering fans. Sadly, neither side can gain an advantage through cooler uniforms or better walk-on music, so you are forced to use more clandestine methods.
You dress up as a fan of the opposing team and mingle with their fans. 'I sure love X team, we are so much better than Y team,' you say over and over, and soon you have penetrated to the core of their seating section. Now you strike. 'I sure love X team, we're so much better since we got Babe Ruth on the roster,' you say to anyone who will listen. Of course, Babe Ruth is not on the roster because he is dead these many years. And that realization and subsequent confusion causes a few fans to cheer less while they try to figure out your strange remark. If you can cause sufficient confusion before your tactic is recognized and deployed against your own side, it may be enough to tip the game.
