From Why Hillary Clinton Thinks Gun Control Can Win in 2016:
Seven years ago, when Hillary Clinton was fighting a grueling Democratic primary battle against then-Sen. Barack Obama, she boasted of duck hunting and championed the Second Amendment. Clinton’s campaign in Indiana sent around negative mailers pasted with rifles, accusing Obama of being weak on gun rights. She talked of learning to shoot a gun as a child.
“You know, my dad took me out behind the cottage that my grandfather built on a little lake called Lake Winola outside of Scranton and taught me how to shoot when I was a little girl,” Clinton said in April 2008. “It’s part of culture. It’s part of a way of life. People enjoy hunting and shooting because it’s an important part of who they are.”
Now she says:
Today, Clinton’s calculus has changed. She has come out this campaign in favor of gun control measures with a vigor that surprised even some Democrats, targeting minorities and urban voters.
…
Clinton is helping shape the national debate about firearms, calling for a “national movement” to “stand up to the NRA” and lambasting Republicans for voting against gun control legislation.
I guess this must be “evolution” in action. I can’t imagine it is because she sees the potential for campaign money in taking a different position.
