She's doing it because, even as her town halls have been very well attended, a lot of people are
rightfully questioning her over her meeting with Assad and refusal to denounce Bannon, and they want to see Trump impeached. She sounds a little hawkish on North Korea, I wonder if anyone has asked her whether she'd support a pre-emptive strike? If she says yes it puts a damper on her claimed opposition to "regime change wars". It's strange that she will meet with Assad herself but has not called for bilateral talks between the US and North Korea.
