In Indiana it is against the law to buy alcohol for off-premises consumption on Sunday. It is also against the law for anyplace other than a liquor store to sell cold beer (although cold wine is apparently a-okay.)
So when legislation comes up that would overturn both these provisions, who do you get opposing it? An unholy alliance of churches who are apparently afraid that people will sneak out before the benediction to get a sixer of Bud before the Colts game kickoff, and package store owners afraid of losing their cold beer monopoly and getting beaten down in fair competition by Kroger.
Politics makes for some unnatural bedfellows.
