These charts reflect the results of a new Quinnipiac University Poll in Texas -- done between May 29th and June 4th of a sample of 1,159 Texas voters, with a margin of error of 3.4 points. Of that sample, 407 were Democrats and Democratic-leaners, and their margin of error was 5.8 points.
Texas is still a very red state. It hasn't elected a statewide Democrat in over two decades, and votes reliably for Republican presidential candidates (including Trump in 2016). But, if this poll is correct, that could change in 2020.
Note in the chart above, there is a Democrat that could carry Texas. Joe Biden has a 4 point lead over Trump. That's statistically significant because it's larger than the margin of error. Elizabeth Warren trails Trump by only 1 point (and considering the margin of error, that is basically a tie).
Amazingly, there are four other Democrats that trail Trump within the margin of error -- Buttigieg by 2 points, and three others by 3 points (Castro, O'Rourke, and Sanders).
These are pretty amazing numbers, and they show that Texas may really be becoming a purple state -- with a chance of voting blue for president in 2020. I think Trump would still have to be considered the favorite in Texas, but with numbers like this, Democrats should be encouraged to work even harder in the Lone Star State.
The chart below shows who the state's Democrats and Leaners currently support to be the 2020 Democratic nominee.
