On this Earth Day, lots of people are talking about climate change, but is that what voters want to hear? Elizabeth Warren recently unveiled her new proposal to make public universities tuition free, and to forgive student debt for those making under $100,000. She also supports an effort to impeach Trump. Amy Klobuchar is talking about infrastructure and privacy, and Eric Swalwell is focusing on gun control.
