Recent polls showing President Trump’s inroads with Latinos have set off a fresh round of frustration and finger-pointing among Democrats, confirming problems some say have simmered for months. Many Latino activists and officials said Biden is now playing catch-up, particularly in the pivotal state of Florida, where he will campaign Tuesday — the start of National Hispanic Heritage Month — for the first time as the presidential nominee.

He added, “If we allow a narrative to take shape that somehow the issues of concern to this growing community are not prioritized, then we risk backsliding in the years to come.”
