Like pretty much everywhere in the US, big Texas cities lean (or, in Austin’s case, are quite) left, suburbs are increasingly very swing, and the rural areas are really right wing but have been emptying out. Texas has a somewhat higher proportion of rural to urban/suburban population than New York State which makes Texas overall a “red” state and New York “blue”, but a current Silicon Valley resident is probably going to feel far more at home in Austin, Houston or one of their closer suburbs than they would in rural western or upstate New York.
