lb>   le nu la djordj ualas cu merko gugde ralju cu na fasnu

{lo nu la djordj ualas cu merko gugde ralju cu na fasnu} means
{da zou da nu la djordj ualas cu merko gugde ralju kei gie da na fasnu},
which is false, since {no da fasnu gie na fasnu}. The problem is that
statements like {xamgu gie nu la djordj ualas cu merko gugde ralju} will
necessarily be false, even if it would have been good if GW were president.
