 The former president, meanwhile, set to take the stage tonight to square off in the first presidential debate against President Biden. ABC's political director Rick Klein on the latest polling data heading into tonight. Both candidates have about the same measure of support. So we did something a little bit different in this 538 Ipsos poll. We asked people who they were considering voting for. So that means you could choose more than one candidate. And what you see here is a pretty low ceiling for both Trump and Biden. They don't get above 45 percent, either one of them. I'm struck by the number, though, for Bobby Kennedy Jr. That's almost one in five voters.
