I POSTED THIS YESTERDAY, BUT IT’S WORTH REPEATING, ESPECIALLY SINCE IT WAS CNN MAKING THE POINT:

Senate Democrats voted unanimously three years ago to support the Obamacare rule that is largely responsible for some of the health insurance cancellation letters that are going out.

In September 2010, Senate Republicans brought a resolution to the floor to block implementation of the grandfather rule, warning that it would result in canceled policies and violate President Barack Obama’s promise that people could keep their insurance if they liked it.

On a party line vote, Democrats killed the resolution, which could come back to haunt vulnerable Democrats up for re-election this year.

Senate Democrats like Mary Landrieu, Jeanne Shaheen, Mark Pryor, Kay Hagan and Mark Begich – all of whom voted against stopping the rule from going into effect and have since supported delaying parts of Obamacare.

Expect to hear about this a lot.
