"His tweets do not appear to follow a direct pathway to most Americans by virtue of their subscribing to his Twitter feed. Instead, it appears that Trump's tweets reach Americans because news and social media gatekeepers propagate, rebroadcast and incorporate them into news and social media streams," says Mr. Newport. "In some ways, then, Twitter functions for Trump much like an old-fashioned press release or press conference statement. Few Americans see or read his tweets directly, but many ultimately hear about them via media coverage or other means."
But it was not until February, Trump's first full month in office, that Republicans' optimism significantly outpaced Democrats," Mr. Newport says.
