One of us complains about Texas because they actually live in this state and are subject to the policies of the government here. And yeah, while the administration (under the auspices of the Texas Department of State Health Services) does advocate for vaccination and runs ads to that effect, it's not exactly surprising that message is undermined by the various statewide elected officials going out and vice signaling on cable news and conservative radio shows.
Second of all, to the extent that the Governor is advocating for the vaccine, that support is also undermined by the fact that he wishes to impede the choices that businesses or local governments would otherwise make in terms of vaccine mandates. These guys all scream bloody murder about big government when in Washington, yet locally, they have absolutely no problem sitting in Austin and issuing dictates telling private businesses how to run their shops.
Again, taking into account these actions, not exactly surprising that, to the extent the advocacy exists, it's overshadowed by actions that come across to a lot of people as being hostile toward getting as many people vaccinated as possible.
