Ok beto lost by 2.6 points to Ted Cruz. Ted Cruz is not a strong candidate and 2018 was a good Dem year, particularly in Texas.
It is extremely unlikely this race will be competitive in 2020.
Since when was Ted Cruz ever a bad candidate? He certainly isn't the most personable candidate, but he didn't have any scandals or major problems that caused the race to be close. Texas just isn't the safe Republican state it was before. Reality bites for Republicans.
Seriously? Ted Cruz consistently underperforms generic R margins because he is viewed unfavorably by even a majority of Texans due to his complete lack of charisma, obvious further political ambitions, and generally annoying attitude that makes him work poorly with others - even within his own party. In what way is he not a bad candidate?
Then what about the State House? Why did it follow more to the Senate race rather than the Governor race in terms of votes? The Republicans only won the State House vote by 5.94% in 2018. That's substantially lower than Trump's numbers and Trump's numbers in 2016 were already bad when compared to previous elections.
When you look at the Congressional House races, the Republicans only won by 3.4%.
This idea that Cruz vs O'Rourke was just "bad candidate vs good candidate" is nonsense. There's way too much data pointing at something else going on.
