The impact of an accent on charisma/persuasion

Five years ago, I moved from the southeast US to the northwest. I took my southern accent with me, and, as far as I know, it's been fine. I've been able to get work, make friends, and mostly function as normal.

My accent is light. It doesn't sound southern to other southerners, but it does sound southern anywhere else in the US. People who have commented on it say they like it (but what else would you say, I guess 😅).

But I'm about to take on something that will require me to be persuasive. I'm wondering what Tildes thinks: will my accent diminish my ability to be persuasive? Should I try to train my accent out and develop a more neutral accent?

I find myself torn. On the one hand, a southern accent could immediately call to mind the stereotypes of the south: stubborn people without much education. Maybe it makes sense to let that go and start on a more level playing field. On the other hand, my time growing up in the south is part of my history. It makes me unique and maybe the upset expectations (if someone hears me and expects me to embody those stereotypes I mentioned before) could make me more memorable.

I generally don't like the idea of filing the rough edges off things, especially when those things are people, but at the same time, I have goals I want to achieve and I'm willing to do what it takes to reach them. So, what do you think?

Edit: I appreciate all the comments so far! For a little additional context, I want to be active in local politics. Not trying to run for office or anything. Not sure exactly where I'll be taking that on yet, but it won't be in the south.
