In 1984, I managed Walter Mondale's campaign for president. Mondale won the nomination after a bruising battle with Colorado Senator Gary Hart and Reverend Jesse Jackson.

As a former presidential campaign manager, I remember the final week of the campaign as being the longest and most important week of the campaign. The week doesn't seem to end.

Although I'd first seen Senator Hart in Aspen, Colorado, at a New Year's Day party in 1987, we hadn't talked.

I strongly favor shortening the campaign season and putting more primaries and caucuses on the same day, preferably regionally.

I salute South Carolina Gov. Nikki Haley and Sen. Lindsey Graham for their calls to remove the Confederate battle flag from the grounds of the Statehouse.

On the road to the GOP nomination, Trump earned the reputation as a good debater by slandering and bullying his opponents, knocking them out with cheap shots and lies. On a crowded stage, Trump got away with these deplorable tactics.
