I live in a lefty state, NJ. It's actually more purple than you've been led to believe. My friend started a GOP Executive Committee in the town over. The town went from Dems running unopposed to almost half the town government being Republican. I asked him how I could do it my town in his Facebook group. I was immediately contacted by the county GOP. I created a town GOP page and have over 60 members in a week. Our first meeting is next week.
Take action! We can take over at the local level. Then we worry about state and national seats. Let's build a solid base they can't knock us off of. Good luck pedes!
