I realize that it's probably way too early for this to be available,
but is there somewhere online that I can see or hear Deval Patrick's
victory speech (the one he gave tonight, not the one from the
primary)?  A video would be my first choice, but even being able to
listen to it again would be great.  Failing that, where can I find a
transcript of the speech?

Wow, the Internet is amazing. Deval Patrick's victory speech has
already been transcribed and posted online. Here you'll find a
transcript of the speech:

A video of the victory speech is here:

My strategy was to search Google News with Deval Patrick's name and a
memorable phrase that I remembered from the speech, "This was a
victory for hope."

Google News Search: "deval patrick" "this was a victory for hope"

I hope this is precisely what you need. If anything is unclear or
incomplete, or if a link does not function, please request
clarification; I'll be glad to offer further assistance before you
