(CNN) -- Both parties have received an electoral politics wake-up call, courtesy of a diversifying America. President Obama won re-election thanks in part to a 52-percentage-point spread among Latino voters, the nation's fastest-growing electorate, according to election eve polling. In the America coming over the horizon, it is practically impossible to overcome such a number and win the race for president. According to the polling by Latino Decisions, Hispanic voters nationally and across every battleground state swung heavily to Democrats. And it wasn't even close. Nationwide, the margin was 75% to 23%. And there were remarkable spreads in the tightest of swing states: 87% to 10% in Colorado, 82% to 17% in Ohio, 66% to 31% in Virginia. (CNN's own poll showed a smaller but still significant spread nationwide -- 71% to 21% -- and in the swing states).
