In my opinion, the HoP celebrates how unique the idea of the US Presidency was. An elected representative of the people that was not a king. It celebrates the office itself,...not any one man. The current President is not the single "star" on the stage. They ALL are equal stars.
Have different Presidents speaking in different shows everyday. Or, if Burbank can't afford that, then just have Lincoln, Walt's favorite, do all the speaking. I'm 100% OK with that.
If THIS tactic can convince Burbank to save the entire HoP attraction?,...then I will be happy to support that.
Burbank, this tactic and change to the attraction should satisfy your political mission and sensitivity goals...AND...keep the vast majority of your paying customers happy at the same time.
