1997 MIT Mystery Hunt Puzzle 4 Solution

The answers to these clues are all too short for the spaces provided. This, together with the six unlabeled blanks at the end, and the fact that the clues can be split into six categories of five questions each, suggest the game show Jeopardy! If you write each answer in the form of a question, starting with WHO IS or WHAT IS, etc., then the answers weill fit. Thus, the puzzle is filled in as follows:

WHO IS OLIVER NORTH
WHAT IS D'ANGELO'S
WHAT IS JULY 4
WHO IS WILLIAM BARTON ROGERS
WHO IS VINCENT LOMBARDI
WHAT IS RANDOM HALL
WHAT IS CANASTA
WHAT IS BIG MAC
WHO IS STACY LAVELLE
WHAT IS JANUARY 12, 1997
WHO IS CHARLES VEST
WHO IS GRANT HILL
WHO IS JOHN SHERIDAN
WHAT IS VANILLA
WHAT IS OCTOBER 28
WHO IS ARIF HUSAIN (as quoted in The Tech in 1996)
WHO ARE THE ORLANDO BREAKERS (NFL team on "Coach")
WHAT IS WORCESTERSHIRE SAUCE

WHAT IS VANCOUVER
WHO IS SHERMAN HEMSLEY
WHAT IS BREAST MILK
WHAT IS SEPTEMBER 1752
WHO IS JANE GOODALL
WHO IS KEN BOWERSOX (The "first pitch", thrown on the Space Shuttle)
WHAT IS KENTUCKY

The categories at the end are then SPORTS, TV, QUOTATIONS, THE CALENDAR, FOOD, and POTPOURRI.

When the letters in numbered spaces are transcribed into the final section, they don't appear to spell anything, but all the consonants precede all the vowels:
THSNFRVLTNRWRCPTNHWSTHFRSTFR
CNMRCNCNGRSSMNFRMVRGNEOOAEOU
IOAYAAAIEAEIAIAAEIAOEAOIIIA
Note that the two bold letters above are swapped as indicated in errata.

These vowels and consonants need to be interleaved, keeping each set in the order given, to spell THE SON OF A REVOLUTIONARY WAR CAPTAIN, HE WAS THE FIRST AFRICAN AMERICAN CONGRESSMAN FROM VIRGINIA. This clues John Langston, and LANGSTON is the answer.
