This is a mixed blessing. No more "smoking gun" hyped-up tape to entertain my visiting Eastern friends. Gone forever. I hope you didn't miss it. An announcer's voice over Nixon's explaining what the president really meant while what he really said was drowned out and fragmented. Or the historical record of Watergate that demonized the press while calling the break-in at Democratic national headquarters a "third-rate burglary" and ignoring the "dirty tricks" campaign. Or my favorite toy at the museum that allowed us to "interview" Nixon by bringing up fragments of self-serving speeches on a movie screen.
The other presidential museums I have visited slipped into this sort of lily-gilding occasionally — for example, the treatment in the Hoover museum in West Branch, Iowa, of the march of many thousands of World War I veterans on Washington to pressure Congress into passing a bonus bill the vets had been promised. The bonus was defeated, and on Hoover's orders, the vets were attacked and dispersed by heavily armed federal troops, an affair treated in the museum entirely through Chicago Tribune headlines calling the march a communist plot.
