INDIANAPOLIS – The liquor store industry has been pulling out all the stops in order to keep a firm grip on selling cold beer—and not allowing convenience stores the opportunity to do the same, USA Today reports. The industry also has been fighting to keep a ban on Sunday alcohol sales.

Long ties to state lawmakers coupled with campaign donations have solidified the strong relationship between the liquor stores and the state legislature. Indiana requires residents own the liquor stores, which gives them an even better in with lawmakers.

While convenience stores and big-box stores are both fighting the liquor store lobby, each has a different agenda: c-stores want to sell cold beer, while big-box stores want to sell alcohol on Sundays. The single focus of liquor stores—to keep the status quo—has allowed them to be more effective in lobbying.

Lately, though, convenience stores have rallied around the cold beer issue, launching Chill Indiana over the summer and storming the assembly with concentrated lobbying efforts. Their efforts have yielded a special panel to study the cold beer issue.

In an about-face, the liquor store industry said last month that it would support Sunday sales, and a senator has announced plans to introduce a proposal for that in January. Also putting pressure on liquor stores to change has been public opinion, which has started to demand changes to allow for more convenience and accessibility to alcohol.
