With the Republican National Convention winding down, how does it stack up with past conventions?
Bob Schieffer would know. The veteran CBS newsman has been covering conventions since 1968. While he says he hasn't seen anything quite like the violence of the 1968 Democratic National Convention in Chicago, he referred to this year's RNC as "the most unusual." He talked to Jasen Sokol Thursday afternoon about the RNC and next week's Democratic National Convention.
