Cruz has never been what I consider to be a savvy politician. His behavior at the 2016 Republican convention was that of a three year old, and not that of a highly educated, experienced individual.
While it is not a forgone conclusion, Trump's winning, I just do not see how the Democommies bring anything at him to unseat him.
The FED could play games and slow the economy, but short of that, Trump wins.
In the end, the big mouths of the racist Anarchist Four, and other voices like Wilson, Waters, Nadler, Schiff, Greene, etc..those voices kill the Dems in 2020. They are all idiots, and truly embarrassing.
