Trump appears to have begun to slow Harris' rise, which began after President Joe Biden dropped out of the race.
At the same time, Harris has abandoned many of her most progressive views that she took during her failed 2020 Democratic presidential primary run.
"She's not really quite sure what she believes that's why she is pretty evasive to answering questions on policy, policy positions that she has supported in the past and supposedly what she does not support now," Wolking said.
Tuesday's debate will mark the first time Harris and Trump will be in the same room together.
With perhaps the exception of the Nixon-Kennedy debate, no other presidential debate will loom larger in history.
