Attorney General Martha Coakley is warning against expanding the Massachusetts Lottery online.


The Democratic candidate for governor said allowing individuals to purchase lottery tickets over the Internet would require credit cards.  And that is the problem.


She said using credit cards to purchase lottery tickets in stores has long been barred in Massachusetts out of fear that it would lure problem gamblers into crushing personal debt.


One of Coakley's Democratic rivals for governor, state Treasurer Steven Grossman, has pushed state lawmakers for permission to test what he hopes will be a first wave of Internet lottery games in Massachusetts.


An aide to Grossman said he also opposes the use of credit cards and that online Lottery games wouldn't require them.
