1. All touchscreen voting machines should allow recalibration in the

process correctly.
    

I'd hate for this to involve the pollworker coming anywhere near the
voting booth.

So, what we need is a recalibration operation that is trivial for the
voter.  One way to do this is to routinely have displays that call for
the voter to touch corners of the display (put the next button on the
lower left corner, the back button on the upper right, for example), and
take pokes at those buttons as calibration hints.
  
I'd hate for many voters accidentally to invoke this mode, or to be tricked into invoking it -- or for someone to program the machines automatically to invoke it under certain conditions.

Many changes intended to "fix" touchscreens introduce further security holes.
