What happened in South Texas?

[W]

How come it swung so hard towards Trump? It looks to me like turnout just shot up for Republicans but by that overwhelming a margin?

South Texas has more assimilated and established mexican populations and they want the illegal immigration problem solved since illegals take their jobs away more than anyone else's. In 2016 they distrusted the Republican brand and dems did well at framing Trump as anti-mexican/anti-latino (the latter explain why Hillary had record margins in Miami-Dade and made inroads with cubans). Now they have experienced 4 years of Trump and saw that was not the case. In fact Trump cared about border issues more than any recent president and his populism made him more palatable to Latinos. They would probably trend R still with a Mitt Romney type since Obama 2012 was the dem ceiling with Latinos but Trump made them trend much faster.

HEGAR wasn't a good candidate, she was a bad candidate, that's why Dems underperformed with her on the ballot where Polls told us the opposite she was a good candidate.

Polls underestimated her strength as a candidate, she lost by 10 not lost by 3

Users said she was a bad candidate before polls showed her pulling even and our suspicions were absolutely correct she was too liberal in TX
