Why Trump's party losing Texas in midterm polls is a big deal?

The Democrats got their first statewide victory in Texas in midterm polls since 1990s as Democrat James Talarico won Senate seat and Gina Hinojosa unseated three-term Governor Greg Abbott. As Republicans lost a deeply red state, it's being considered a rejection of Donald Trump's policies. Experts say it also reflects dissatisfaction over rising energy costs, foreign policy, and Iran war.
