[EM] A variant of DSC

[fsimmons at pcc.edu]

Last night I realized that my example below shows that my variant of DSC fails later-no-harm.

In my modification of 
DSC A1 wins.  If the A2 faction truncates A1, then the solid coalition with the greatest support is just 
{A2}, so A2, wins.  This means that "later" does indeed harm A2. Therefore, like DAC, my modification 
of DSC fails later-no-harm.

Does my modification of DAC fail later-no-help?
