Regardless of who wins the primary, the key to electing a new governor is managing to get the same voter turnout as the presidential elections. A gun friendly candidate doesn't have to win Chicago or Cook Co., they just need to get 20-23% of the vote there.
With the current climate of dissatisfied voters in some wards, this might be the best opportunity to elect a pro-2A candidate but the key will be voter turnout. Go vote and get your family and friends to vote.
