End the "Blue Laws"

The Minnesota Monitor is reporting:

A bipartisan effort is under way to end Minnesota's "blue laws." As state laws currently stand, Minnesotans who want to do their car shopping on the weekends or buy beer for a Sunday night party have found themselves out of luck. The selling of strong liquor or automobiles on Sunday is currently against the law in Minnesota.

Unfortunately, it doesn't sound like they are optimistic on getting the job done:

Ultimately, the bill is mostly symbolic and intended to generate a discussion. "We don't expect these bills to get out of committee, but we wanted to let people know that these silly laws exist," said Kahn.

I don't understand at all what is hard about repealing these backwards-ass laws.
