WASHINGTON _ Carlos Curbelo's low-lying and Democratic-leaning Miami-to-Key West district is ground zero for a blue wave in November.
But he's built a sizable sea wall.
With 2 { months until Election Day, polling from Republicans and Democrats shows Curbelo with a lead over his likely Democratic challenger Debbie Mucarsel-Powell in a district that Hillary Clinton won by more than 16 percentage points over Donald Trump, and Curbelo isn't running television ads yet.
