The 64-year-old Danville artist, who survived breast cancer, has purchased health insurance for herself for decades. She watched her Anthem Blue Cross monthly premiums rise from $317 in 2005 to $1,298 in 2013. But she found out last week from the Covered California site that her payments will drop to about $795 a month.

But people with no pre-existing conditions like Vinson, a 60-year-old retired teacher, and Waschura, a 52-year-old self-employed engineer, are making up the difference.

“I was laughing at Boehner — until the mail came today,” Waschura said, referring to House Speaker John Boehner, who is leading the Republican charge to defund Obamacare.

“I really don’t like the Republican tactics, but at least now I can understand why they are so pissed about this. When you take $10,000 out of my family’s pocket each year, that’s otherwise disposable income or retirement savings that will not be going into our local economy.”

Both Vinson and Waschura have adjusted gross incomes greater than four times the federal poverty level — the cutoff for a tax credit.
