they say they're different. but the next debate will provide an interesting side-by-side of those candidates in that effort. what we've seen in iowa has been an interesting display of how two work together. you have joe biden and bernie sanders, feeling pressure from their first debate, using each other as a foil to gain momentum. you have joe biden to start the week, talking about his vision for building on the affordable care act. obamacare 2.0. to expand access to people. and criticizing bernie sanders and medicare for all. saying it's not an option and too expensive. bernie sanders has been pushing back, eager to take on that debate against joe biden. talking about this, is the best option for seniors.
