Podcast: How has the political environment changed & what does it portend for Senate races?

On August 10, in the Oval Office, Donald Trump signed an executive order telling American parents to break the measles, mumps, and rubella shot into three separate injections and to space childhood vaccines across many more trips to the doctor. He said the change would "align the United States with other advanced and developed nations." That line is the whole argument, and it is false. No advanced country gives measles, mumps, and rubella as three single-disease shots. The vaccines do not exist in that form anywhere. A parent who wanted to follow the new American recommendation could not, because there is nothing to buy.

This is not a small drafting slip. It sits at the center of the case the White House is making, and it falls apart the moment you look past America's borders.
