Depends on the news outlet. The AP is pretty conservative in its calls, even when they’re early like this, so they typically aren’t the ones to have to retract. That’s more often the news networks like CNN or Fox. Some outlets want the scoop and take more of a risk (calling at 80% likelihood or whatever) while others wait for 90 or 95% so they can present themselves as more reliable. Both are calling what’s likely, but in the former, every now and then you’ll get some races wrong. For the higher percentages it’s much more rare.
