Romney was in shock when Obama was declared the winner according to several news articles
Because he had good reason to think that the eight million white voters who stayed home but had voted for McCain would turn out. Instead, Obama's attack ads convinced them that Romney wanted people like them to die.
He also underestimated Chicago & Philly-style fraud & intimidation in key states.
He's infinitely better at numbers than you, but naive about politics.
Eight million white voters who stayed home? What happened to all of the ENTHUSIASM that white voters were alleged to have towards the GOP this year? It turns out that any added enthusiasm this year was on the part of LATINOS and for the most part, thety wanted nothing to do with Romney. Latinos of course continue to be an increasing percentage of the electorate.
This year, Obama became the first man who lost the white vote by a double-digit percentage to nevertheless win the election. That's because honky voters constituted a record low 72% of the turnout.
