Interesting. I just found out that the same White House official, Jeanne Lambrew, who got confidential tax info for White House purposes is the one in charge of ACA implementation. I'm not one to be paranoid about privacy issues, but in the wake of Snowden's revelations and certain IRS actions in the past few years, I'll probably be leaving some questions unanswered the next time I'm visiting the doctor.
One doesn't have to be a Republican to distrust the current administration (though it helps not to be a Democrat because it's much harder to see the faults in people we are affiliated with) and government expansion into the nonpublic details of our lives. I used to think libertarians were nuts; while I don't agree with everything they stand for, I admire them now for standing up for liberty and against government overreach.
