It was actually rather well-suppported even by the Left right up 'til the press turned on Johnson after the Tet Offensive. But it was not just the press (Which was a much narrower field of the three big networks, major metro newspapers, and about three main news magazines) or those simply following the lead of the press, because by the end of '68, enough info was seeping out of the services about ridiculously-self-defeating ROE and political restrictions that a lot of people, even on the Right, were beginning to seriously question whether the crazy bastard SOB LBJ and his criminally-militarily-ignorant SECDEF McNamara had the slightest clue WTF they were doing, and getting so many young men killed.
