I don't think the independent voter will stand for much tinkering with these retirement accounts. I think you would see the same type of voter backlash we have with the attempted health care grab.
I'd think it would be greater, at least I would hope so. This wouldn't be mere 'tinkering', it would be, in effect, outright confiscation. A very dangerous, peronist way of economic management. But then, it might be 'fairer' to our grandchildren, taking money we've earned twenty years ago and burning it now. Kind of gives a sort of immediacy to the problems that are out there today.
I absolutely consider that their belief is along the lines of "if we pass it (IRA confiscation or, indeed, any other part of their Fascist/Marxist agenda), it won't ever be repealed whether we're still here in the Regress or not".
