The question then becomes, could any
truly huge tsunami (or even a series of huge tsunami), regardless of the
cause, do sufficient damage world-wide to kill off the dinosaurs (recalling
that dino fauna have been found in South America, in the arctic, in the
American west, in Australia, etc.) Right off the bat, it doesn't seem
plausible.

Throw in the demonstrated fact that dinosaurs were living in
mid-Arctic latitudes in the mid-Cretaceous and it gets very hard to argue
that there were *no* dinosaurs in upland areas in the summer hemisphere at
the time of impact/ tsunami, and it gets really hard to sustain the argument.
The point for the asteroid impact hypothesis is that a "asteroid
winter" could last *several years*.
