CHARLOTTESVILLE, Va. — Consumers here at first did not believe the health insurance premiums they saw when they went shopping for coverage this month on HealthCare.gov. Only five plans were available, and for a family of four with parents in their mid-30s, the cheapest plan went typically for more than $2,400 a month, nearly $30,000 a year.With the deadline for a decision less than a month away, consumers are desperately weighing their options, dismayed at the choices they have under the Affordable Care Act and convinced that political forces in Washington are toying with their health and well-being.“I believe in the Affordable Care Act; it worked for me under the Obama administration,” said Sara Stovall, 40, who does customer-support work for a small software company. “But it’s not working as it was supposed to. It’s being sabotaged, and I feel like a pawn.”
