Cruz never shut the government down. Only the Executive can do that.
As I said Cruz is easily ignored and his Senate colleagues did just that.
The essence of leadership is FORCING attention be paid.
You are correct it was Obama that actually shut down the federal government in some forms, due to the Senate and Congress refusing to allocate an increase in spending for that fiscal year. And that effort was led primarily by Ted Cruz. Even you can admit that. There weren't too many other people trying to stop the increase in debt limit. Just Cruz and a few other senators , and half of the house. Did trump have anything to say or do to offer support or help? But I am glad trump is finally supporting Cruz ( and other republicans in the past) efforts to sell federal lands to pay off the federal debt. Awesome. I am glad some trump supporters and cruz supporters can agree on that at least.
