No, it's not. Democracy comes from Greek dēmos (the people) and kratia (rule). In the context of this thread, Texas will take away any potency of the vote of the majority of people, and hand it to the minorty who live in sparsely populated, rural counties
The government that hands all voting power only to those that support it have totally abandoned even the pretence of democracy. Nobody committed to real democracy could ever accept such an abomination.
And do you know why they're doing it? Because Republicans know full-well that they cannot win elections any more when elections are run according to true democratic principles. THis is because the majarity of Americans do not like their policies. But rather than change their policies to appeal to the electorate, as real democrats would do, they have to cheat, and find ways to ensure that only the votes of their supports count.
Of course, if you are a supporter, no doubt you will approve. But beware the day (and it will come) when the absolute power thus acquired goes too far and becomes tyrannous -- because their will no longer be the democratic power to stop them. And that day will come. Power tends to corrupt, and absolute power tends to corrupt absolutely.
