A couple ideas for you:
Work on easier people, tons of people are only a couple good conversations away and are a better use of your time. I know it is tough cause it is your mom but definitely something to consider.
Get away from the two party discussion. Focus on concrete issues she faces and ask a lot of questions on how she thinks it should be handled. If she is a hard work and no handouts sort who has had factory experience maybe unions could be an in. Or ask about what she considers the minimum acceptable lifestyle and dig in to how to get society there for all, even the hardworking and down on their luck. Like what hoops is she willing to jump through if she got hurt or sick.
