I think the leadind Dem in the race for Flake's seat is Rep Kyrsten Sinema who once claimed to be the first bi-sexual woman in Congress. The Republican I like is Rep (Col) Martha McSally who flew A-10s for the Air Force. Here is a short quote from wikipedia:
In 2001, she successfully sued the United States Department of Defense in McSally v. Rumsfeld, challenging the military policy that required U.S. and U.K. servicewomen stationed in Saudi Arabia to wear the body-covering abaya when traveling off base in the country.
Sheriff Joe Arpaio has also announced he is runnung but I am not sure the senate needs more 85 year olds.

Personally, we are recovering from a water leak in the slab. Six weeks later the plumbing has been re-routed, tile replaced, drywall replaced, textured, and painted. The workers have left and we are cleaning up from the mess. While this was going on, I flew to Miami to elp my mother get her roof and A/C replaced in preparation to selling her house. She is moving to a retirement center in May(?). She is turning 88 and this is a good move for her. In April we will drive to Miami and help her do more repairs to get her house on the market. Our up-dating will not be as extensive as you did for your father because this project is 2500 miles from home and needs to be finished quickly.
Thanks for your interest, but it continues to be a busy first half of 2018.
