You can help save the ACA (aka Obamacare) in the Senate by helping to foil the Republican efforts to smuggle the bill through the Senate unseen.
The Indivisible folks have a website that lets you file an amendment to exempt yourself from the strictures of the Senate’s version of Trumpcare. Whatever the GOP bill ends up proposing, you can help stall its progress by asking your Senator to file and debate an amendment exempting you, as an individual, from its (very mean) provisions. You can also add other comments, which will be entered into the Congressional Record to say why you think Trumpcare is an abomination.
So, in the interests of all of us, help run out the clock. Go forth and ask for an exemption — just for you.
