The principles expressed in your post are important. Cruz has a responsibility to his Texas voters if only because they selected him to represent them.
Publicly recommending in the face of threatening weather with expected shortages that his voters remain quite uncomfortably at home (as he did according to news reports), and then flying off to a sunny resort beach is not the action of a competent leader.
It is true the quality of his representation and how he regards Texas voters may not be a huge issue for you or the rest of us, but that is only until we at the national level are asked to vote for him.
A responsibility that Ted Cruz has taken very seriously over the past 8 years. That is why he wad reelected in 2018.
We don't need some fake, made up crisis from the fake news media to cover up all the great work Ted Cruz has done as a Us Senator.
