Ted Cruz's Hyperbole

Here's Ted Cruz on Meet the Press today indicating what will happen if Hillary, Bernie, or Donald becomes president and appoints a US Supreme Court Justice to replace Antonin Scalia:

The consequences are: (1) "unlimited abortion on demand" (2) "Religious liberty torn down" (3) "Second Amendment taken away" (4) "Veterans' memorials torn down" (5) "Crosses and Stars of David sandblasted off the tombstones of our fallen veterans."

Shouldn't his assertions have been challenged? How does the press perform its duties if statements like these are not challenged? Another institution that is not performing as it should.
