(CBS News) HOUSTON - The theme of this year's National Rifle Association convention is "stand and fight," and organizers expect nearly 80,000 members to attend this weekend's meeting.
Many members are energized by the defeat of a senate proposal to expand criminal and mental health background checks for gun buyers at shows and on the internet.
found 88 percent of Americans support background checks, and 11 percent oppose them.
But not all NRA members are against background checks either. Elvin Daniel's sister, Zina Daniel, was murdered by her husband in a Wisconsin spa last year.
Two other women were also killed in the attack.
"I am here, I am an NRA member, I'm an avid hunter ... I own guns, I enjoy shooting guns with my family, but, I think we need to do a background check," said Daniel.
However, David Keene, president of the NRA, disagrees.
"Those are very, very complicated and very difficult and very restrictive kinds of proposals that we are not going to support now, ever," said Keene.
Daniel has been walking around the convention, trying to convince other NRA members to support expanded background checks, and to make it clear that the bill would ban a national gun registry.
"People don't know the truth about what's in these bills, somebody needs to explain it to them," said Daniel.
"If we can prevent what my family went through, we owe it to ourselves to do so," he added.
