A colleague asked yesterday what someone could do to support the candidacy of a particular person for NASA administrator. (The topic had apparently come up on a mailing list he was on.) The only suggestion that came to mind was to call the White House comments line (202-456-1111) and tell them who the President should nominate for the position. Emailing the White House is another option, but likely far less effective: can you imagine how much spam email@example.com gets?
I would be curious to get some expert opinions on alternatives that might be more effective, or whether any such efforts would likely be ineffective or even counterproductive.
