A message from Senator Charles E. Schumer

[MrBehemoth]

I wouldn't worry about it too much. If you're concerned, just change your passwords and don't reply. Politicians were bound to learn how to spam eventually.

I wouldn't be concerned about it knowing your nick - it's easily scraped. I would have been more concerned if it used your real name.

I am, likewise, not in the US, but in the last US general election Obama himself sent me a personal email. We're now best buddies.
