Sunday hunting is wrong for waterfowl...period, unless the feds give more days, and I really don't care to hear all the old, worn out pleas about the working stiffs, etc. I could care less about all the other species...you can hunt them all you want 24/7 for all I care. But Sunday hunting for waterfowl the way the bill is written will cut my season by over 15%, because I have absolutely NO access to private land. Ans most of the "working stiffs" out there don't, either, and will gain nothing from the bill.
As for how the legislator votes, that's part of his candidacy when he runs. If his constituents don't like it, they can vote for somebody else next time. Every time somebody runs for office in this country, he is elected...supposedly...for his personal views. If his views most closely coincide with yours, he's your man. If not, you vote for his opponent. Basic politics.
