I recall TV "news" reporting -- I recall that there were days when nothing else was mentioned on the network news. They repeated charges against Nixon, et al. that had been new days ago.
It was a 24/7 frenzy.
.. and nary a word from the networks a few years earlier about the EXACT SAME THINGS (and worse) done during the JFK and LBJ administrations.
I worked with younger folks at the time and everyday they'd be repeating the latest TV network "news" about that "bastard" Nixon.
I think that that is "apples and oranges." The majority of voters are apolitical.. they are influenced by "nonpartisan" media, familiarity with the candidate's name, friends, relatives, and maybe those silly ads.
People with opinions, biased or otherwise, about news sources pay attention.
The newspaper employee should have the courtesy to spend a little time listening to conservative media.. he will find that the conservative media will be many times more likely to state proudly that they are biased in how they interpret facts. The left is much more like to say, "there is no argument the facts are in."
Really dark things were done with nary a murmur from the press. For example, J. Edgar Hoover hounded ace FBI agent Melvin Purvis out of the agency and then, afterward, continued to bug him and harass him until he committed suicide. That was the blackest thing Hoover ever did, and it was truly worthy of a jury. But the press never touched it.
Lyndon Johnson used Hoover to bug Barry Goldwater, including, it was said, Goldwater's campaign plane. The "take" was turned promptly to Johnson's "Five O'Clock Group" (his dirty-tricks team) who exploited the FBI's information. We heard about this after the election, but it never generated the indignation, much less the firestorm, that was ginned up for the hated Richard Nixon during Watergate. Incidentally, Nixon's intention in having the DNC offices wiretapped were comparatively modest: He wanted urgently to know of any indication that Sen. Edward Kennedy would enter the 1972 presidential race.
Nixon was barely a Republican, was pretty Democrat acting, yet the news media absolutely despised him. That cryptic property of the leftist media doesn't bode well at all for Mittens.
