The shaping of opinion happens in subtle ways.
Donald Trump has hired a pollster, something he spurned in the primaries as not necessary in his seat of the pants strategy that worked. Now hiring pollsters is not unusual as candidates craft strategy. Heck there was polling in last year's city races.
But in making the change to a more big time campaign, the anchor on MSNBC this morning declared that Trump had "flip flopped", a generally pejorative term.
Just a subtle way the corrupt media can shape opinion.
