The Initiative and Referendum process only have one negative feature. They are simple majority decisions. This simple majority rule has lead to the abuses. Politicians and special interests have resorted to the initiative and referendum process to avoid the super-majority rule with regard to increasing taxation.
A recommended change would be to require super-majority approval when the issue involves an increase in taxation or requires significant government expense to implement without a indentified, dedicated revenue stream to offset the expense.
If a super-majority rule where imposed, the number of initiatives would be reduced dramatically.
