Fifty years ago, journalist David Broder described Ronald Reagan’s speech on behalf of presidential candidate Barry Goldwater as “the most successful political debut since William Jennings Bryan.”

The speech entitled “A Time for Choosing,” has echoed in American politics for more than 50 years, defining a new approach to conservatism giving us optimism in the underlying greatness of America.

This televised campaign address by Ronald Reagan made for the Goldwater Presidential Campaign was made on October 27, 1964.
