How? "These people are stupid" that's how.
A. They / Podesta planted/paid Manafort who turned and won POTUS the Delegates' nomination; B. they depended on Flynn / Rodgers / McMasters who all turned; C. Their own Village Idiots hand-picked for Willingness To Rig educated in America had zero understanding of the Electoral College D. their inflated belief in The Narrative / MSM "power" further ignored / marginalized the needs and intelligence of We The People E. Their Hail Mary by Obama parading around with his Elitist Preening in the 11th hour further insulting the intelligence and integrity of Normal Americans threw Real America an EASY interception in the endzone of TRUTH and POTUS was off and running~
Oh and PS their incessant "spinning" vs The Truth (think HRC Cough&Faint) proved to electoral voters the Better Choice of the MAGA truth~
