I live in Virginia and I was proudly told this by a Republican running for office. They have a DB so they can pool data state-by-state and cross-reference it with social media.

My advice if you don't believe this is true, just ask! They are very open about talking about this and feel that Democrats do the same thing.

I live in Ohio, can confirm this is false. Every state representative I've met with has been happy a citizen is taking interest in local politics and has been open to a conversation. A state rep is not going to target you house or street (not even sure how this would happen) because they disagree with you
