The Senate plans to hold a Motion to Proceed vote this Tuesday on some kind of healthcare bill. This thread explains it well but the key thing here is that McConnell thinks he can pass something, there aren't currently enough publicly committed No votes to stop him, and if you haven't contacted your friends in states with swing Senators, you had better do so today.
Re-contact people you've already had conversations with and ask them to call again.
It's especially important to contact people in Alaska and Nevada, which you can find by using Facebook search for "friends in Alaska" or "friends in Nevada."
