Warning billionaire former mayor and gun control advocate Michael Bloomberg is "not going away," the National Rifle Association is hoping to fire up members to help elect a GOP-controlled Senate.“We fully expect to win a pro-gun Senate in this cycle,” NRA president Jim Porter told the Washington Examiner in an interview published Monday.“It is vital certainly to our issues, but it is vital to the well-being of this country."Porter's remarks came at the start of the NRA's "Great AmericanOutdoor Show."Former NRA head David Keene told the newspaper the group will be spreading the word to supporters about the importance of the election — and that those supporters “know what the opposition is, they know how close it is in the Senate, they know that the Supreme Court could be at stake in the next few years.”NRA spokesman Andrew Arulanandam also told the newspaper the group's efforts with supporters is aimed to counter Bloomberg's expected gun control lobbying. “Bloomberg is not going away," Arulanandam said. "What he’s going to do is double down. This is definitely not over yet we still have a lot of work to do, with emphasis on ‘a lot’."Keene added the NRA has made a difference in close elections, and it's preparing an education campaign to reach as many as 50 million supporters, the newspaper said.The Great American Outdoor Show in Harrisburg was cancelled last year after sponsors organized a boycott because the former organizer banned the AR-15 from displays following the Sandy Hook Elementary School shootings, the Examiner noted.
