In the famously red state of Texas, Republican state legislator Jason Villalba  of Dallas last week offered a frank assessment of the crossroads at which his party finds itself.
[T]he time has come closer when we will see the sleeping giant [of the Hispanic electorate] awaken and it will make a tremendous difference in our ability to win elections if we cannot win the votes of our fellow Hispanics.
Even as the country rapidly becomes more diverse, the GOP has clung to its strategy of alienating Latinos , African Americans , women , and LGBT people with an endless barrage of outrageous statements  and discriminatory policies .
As some Republican leaders , like Villalba in Texas, are noting, this tactic isn’t good for the GOP. Demographic changes , though small on the surface, could have major political impacts, particularly in swing states, that will make it harder and harder for Republicans to win important elections.
In Texas alone, analysts are projecting a two percent increase in the Latino electorate for the 2016 election cycle compared to 2012. That kind of increase is still relatively minor in Texas, but a similar shift could make a crucial difference in swing states like Florida, Colorado, and Nevada. As GOP pollster Whit Ayres notes 
Changing the demographics of the state by two percentage points puts a finger on the scale in each of the swing states for the party that’s doing well among Hispanics. This underscores the critical importance for Republican candidates to do better among nonwhite Americans, particularly among Hispanics, if Republicans ever hope to elect another president.
Some far right activists argue that the GOP can win by increasing its share of the white vote , but the numbers don’t bear that out. As Resurgent Republic  noted, “every month for the next two decades, 50,000 Hispanics will turn 18.” Without appealing to those voters, Republicans face a steep climb to victory in any national race—and a quick journey to minority party status.
No wonder the party is so fond of strict voter ID laws, restricted early voting opportunities, and proof of citizenship laws to deter certain people from coming out to vote.
