The Wyoming Senate gave preliminary approval to a bill that would allow a lottery and multi-state games such as powerball in the state. The senate approved the bill by a vote of 17-12 on Wednesday afernoon. Supporters of the bill say Wyoming residents already are playing the lottery, spending millions of dollars in neighboring states on tickets. Lottery opponents say it's a form of gambling and a tax that disproportionately affects the poor. The bill already passed the House and faces two more votes in the Senate.
