From the Sun Belt battlegrounds of Nevada and Arizona to sprawling turf wars in Texas and Florida, there are signs that the Hispanic vote — which party leaders have long hoped would be the foundation of future electoral success — has yet to flourish in their favor this year.

Although President Trump and Republicans have embraced policies and rhetoric hostile toward Latino immigrants, including fresh plans under consideration to separate migrant families at the border, Democrats have struggled to generate enthusiasm for their candidates in some Hispanic communities.

Democratic strategists and officials have pointed fingers at fellow Democrats, blaming congressional campaigns and allied groups for failing to engage Latino voters strongly enough as they place a heavy emphasis on winning white, middle-class voters in suburban swing areas.

In some races, stronger-than-expected Republican appeals to Hispanic voters have complicated matters further for Democrats, leaving them scrambling to compete in diverse areas key to determining which party controls the Senate and House.
