I knew it!

It took watching 1½ episodes of The Amazing Race with full attention to figure it out, but my instincts weren't wrong: racer Jason (of team Lorena and Jason) is the Jason Widener who played a younger version of Jed Bartlet in The West Wing season 2 season finale, "Two Cathedrals". He sounds exactly the same.

Man, I've watched way too much "Two Cathedrals" than is normal.
