'As goes Texas, so goes the country': Bernie Sanders on turning Texas blue

AUSTIN (Nexstar) -- College lecture halls up and down Texas' "Blue Spine" attracted a who's-who of national progressive icons this week -- Bernie Sanders and Alexandria Ocasio Cortez headlined rallies with Greg Casar and Beto O'Rourke to drive youth turnout, spreading an unapologetically progressive message from which most Democrats running statewide in Texas have shied away.

Colin Allred and Kamala Harris, for example, campaigned against fracking and for a Medicare-for-All plan when running in Democratic primaries.
