Tonight's presidential debate -- the second between Donald Trump and Hillary Clinton -- at Washington University in St. Louis is one we're watching closely.
Here are three things you should keep an eye on:
3. Mic check?
Trump had a point. The Commission on Presidential Debates later admitted that there were "issues" with his audio during the first presidential debate. The New York businessman complained about a defective microphone after the debate. We will see if Trump has a different debate performance, assuming the audio issues are resolved.
2. The topic of health care
Clinton and Trump did not touch on health care during the first debate, but we can expect it to be a topic Sunday. Why? Former President Bill Clinton on Monday called the Affordable Care Act the "craziest thing in the world," prompting pushback from Republicans, including House Speaker Paul Ryan.
Going to have to agree with Bill Clinton on this one... https://t.co/2k3LSplmER

1. Appealing to the early voter
What arguably makes this debate so critical is the early voter. Early voting has already started in at least 10 states, so independents and/or those on the fence about either Trump or Clinton may use Sunday's debate performance as a deciding factor. In Arizona, early voting starts Wednesday, long before the last presidential debate in Las Vegas, which is scheduled for Oct. 19.
Watch the debate live TONIGHT at 6 p.m. on ABC15.
