It isn’t as if some autocratic ruler has denied us access to candidates' more meaningful utterances, such as stump speeches.  What’s blocking us is the structural limitations inherent in the nature of our existing news media.

To begin with, the media have trouble figuring out when to call a stump speech news.

Typically, such a speech is first tried out long before the primary season is seriously underway, and it tends to persist with only evolutionary changes throughout the length of an election season.  Do we expect a news organization to devote always-scarce resources to presenting a political speech that is delivered well before the primaries themselves are much in the news, often to a rather obscure audience, and even more frequently by a person who has yet to emerge as a serious candidate?

On the other hand, if the news organization waits until later in the campaign, the speech isn’t really new anymore, and its news value tends to be diminished correspondingly.

Another structural issue involves the timing of access by the public.  Contemporary news outlets have extremely short "shelf lives."  Television and radio programs vanish into the ether literally as soon as they are broadcast;  newspapers and newsmagazines disappear from the newsstands in a day or a week.

Say a news outlet decided to carry one or more stump speeches.  In which fleeting edition would this make the most sense?  Given that the speeches would not be breaking news, the choice of an issue or program would have to be somewhat arbitrary.

How would the public find out about this arbitrary decision—and in sufficient time to either tune in, or buy a copy before it left the newsstands?

Also, what about people who might not be interested on the particular arbitrarily-chosen day that the speeches are presented, but might well be willing to check them out at a different time?

This is at root a problem of trying to force audience interest that is not time-sensitive into communications media that are.  It mismatches the demand for information and its provision to the public as poorly as if a restaurant only broadcast its menu in television commercials, and failed to provide printed copies to its patrons as they sat down at their tables.
