A very interesting minor story on the wires today. President Trump has withdrawn the name of Rep. Elise Stefanik to be UN Ambassador. That isn't what is unusual, other names have been withdrawn.
What makes the story news is that the White House concluded she was more valuable to its policy goals staying in her House seat representing upstate New York. The Republican majority in the House is so slender that literally every vote counts.
A poor turnout in a special election to name a successor for her seat could be won by a Democrat. So whoever gets the UN job won't be a sitting member of Congress.
