Texas is a red state that Democrats have been salivating over for years now. It’s considered a Republican fortress, and many an attempt has been made to turn the state into a blue one, and for multiple reasons.
If they manage to turn Texas into a Democrat state, then not only will Democrats have a very large territory by which to push their agenda and utilize the cash it has to dole out free stuff to secure even more votes, it’ll be a massive blow to Republican morale.
This is why the left has spoken so highly, and very publicly, about figures like Robert “Beto” O’Rourke, the Castro brothers, and Wendy Davis. They put a lot of time and effort into making these people look like heroes who will turn the tide in Texas and bring about an age of Democrat rule in America.
