Is it just arbitrary, or an absurd "mine is bigger than yours" thing?

I think it's the latter. The prez is arguably more important than the
second
fiddle, so he gets a bigger TFR.

the reason is probably more related to the perceived publicity
"benefit" of hitting the president being more spectacular than
hitting the VP.

Note that part of the purpose of the terrorist is to make
a public statement wrt the fact that the US can be attacked
rather than trying to inflict actual damage.
