Los Angeles City Council candidate Raul Claros is taking his campaign straight into the middle of what many residents call the city's biggest embarrassment: MacArthur Park. The District 1 challenger rolled a 30-foot RV into the park Friday and announced he plans to spend the weekend there. "This is how committed I am," Claros told The Post. "I'm willing to stay here in MacArthur Park if that's what it takes for people to take this seriously."
