this is what american voting used to look like. in this george bingham painting from 1852, notice the happy voter and the lower left-hand corner. voters used to drink whiskey provided by the candidates. >> today i want to take a moment to look back with gratitude and admiration to david brinkley who launched "this week" more than 20 years ago and led it with the skills that made him a news legend. and to my abc colleagues sam donaldson and cokie roberts, who put their personal stamp on sunday morning with their trademark blend of insight, intelligence and wit. i hope i'll do the same. that's all for this sunday. until next week, that's "this week." >> it is amazing to see the progression and the history. it's really cool to look back on stuff like that. and that sunday show started back in 1960. it was then called "issues and answers." one of the early hosts was howard smith. we've come a long way. >> absolutely. and coming up, the police officer stepping up on the job.
