OVERNIGHT TECH: Internet tax ban introduced in House

OVERNIGHT TECH: Internet tax ban introduced in House - The Hill's Hillicon Valley:
"THE LEDE: A bipartisan group of House lawmakers introduced legislation on Thursday to permanently ban state and local taxes on Internet service.

Their bill, the Permanent Internet Tax Freedom Forever Act, would also ban multiple and discriminatory taxes on digital items such as emails. It would not ban taxes on online sales. 

Congress passed the Internet Tax Freedom Act in 1998 to put a moratorium on Internet service taxes. The law has been extended three times, but is scheduled to expire next year. The Permanent Internet Tax Freedom Act would extend the law indefinitely. "
Why are Michigan republicans supporting a new tax increase just as national republicans are planning a permanent ban on internet connection taxes?
