- When Trump tapped JD Vance as his running mate, the Ohioan's background was a major selling point.
- But new CNN data shows Vance with a double-digit net unfavorable rating across the Midwest.
- Vance's national rollout as the GOP vice presidential nominee has so far been a rocky affair.
Ohio Sen. JD Vance's national introduction as former President Donald Trump's running mate has been less than ideal.
