Presidential conventions can be memorable for floor fights and bloody battles on the streets outside, or for scenes that stand out as outlandish or awkward. The Republicans gather in Milwaukee this week amid relative party peace. High drama could come next month, though, as the Democrats meet in Chicago with some clamoring for President Joe Biden to leave the race. From Ted Cruz being booed to Clint Eastwood haranguing of an empty chair to Al and Tipper Gore's uncomfortably long kiss and pitched battles between police and protesters outside in Chicago in 1968, conventions past have produced many memorable moments.
