Carrie Underwood has found her voice on Twitter.

The country music star and former “American Idol” champion admitted 31 / 2 years ago that she was afraid to join Twitter, but since deciding to take the leap in 2011, she has embraced the social media tool in ways that go beyond fan engagement. Recently she used Twitter to oppose the “Ag Gag” bill in Tennessee, reaching out directly to Gov. Bill Haslam (R) with a boldly worded message saying that if he signed the legislation, “he needs to expect me at his front door.”

It was the first time she’s taken a political stand so publicly, and it seemed to have an effect. Haslam contacted Underwood to discuss the issue and went on to veto the bill, which opponents said would have stopped investigation of animal abuse on farms.

“He really just wanted to hear everybody’s point of view, which I really respected,” Underwood said in a recent interview. “So it’s kind of neat that [tweet] led to that, which was really cool.”

Dave Smith, a spokesman for the governor, said that Haslam spoke to people on both sides and that Underwood’s was the only celebrity counsel he sought.

Underwood also recently declared “Hug a soldier day” and puts her support behind movements such as the “End It” anti-slavery campaign and animals rights. She has 2 million followers.

“Anyone that knows me knows that I’m a thinker and I’m a planner and I would never weigh in on anything unless I know the full story on it,” Underwood said. “So I do my research. I don’t think I’m a bandwagon kind of person. People are always retweeting sort of weird stuff. I do my own research. I’m not a political person at all. I doubt anyone can tell you what party I mostly affiliate myself with. But that was just something that was in my back yard.”

As you might expect, there was pushback. Rather than shrink from it, she responded with some grit.

“I realize it’s not necessarily so scary,” she said. “Most of the comments I get back on anything are positive. There’s the occasional negative one, but I enjoy blocking that person.”
