Hillary took the documented, legal immigrants for granted.

Lagging support among Hispanic voters for Hillary Clinton and congressional candidates in crucial races has stoked deep concern that the party and the presidential campaign are doing too little to galvanize a key constituency.
While Clinton holds a significant lead over Trump in every poll of Hispanic voters, less clear is whether these voters will turn out in numbers that Democrats are counting on to win. Clinton trails President Obama’s 2012 performance in several Latino-rich states including Florida, Nevada, Colorado and Arizona. In those same states, where Democrats’ goal of retaking the Senate hinge, some down-ballot Democrats remain unknown to many Hispanic voters.
That reality has prompted a flurry of criticism of Clinton’s and the party’s Hispanic strategies. Despite a uniquely favorable environment with Republican Donald Trump’s repeated attacks on undocumented immigrants, Democrats are increasingly worried that the opportunity is slipping away to meet a longstanding party goal of marshaling the nation’s growing Hispanic population into a permanent electoral force. The concerns are compounded by Trump’s recent surge in several battleground states.
