Does one necessarily need to add an asterisk indicating that a selection is
required for a radio button selection form input?
It seems to me that one can argue two ways:
1.) The fact that some item in the radio button group will always be
selected tacitly implies that the input is required. It is really impossible
for the User not to mae a selection, so why bother to indicate that it's a
required field?
2.) Nevertheless, the required field asterisk draws the User's attention to
the field input itself and the fact that there is potentially a decision to
be made.
