If Harris can keep the energy and enthusiasm levels high and the Democrats pick a good VP they can beat Trump.
She will perform better in a debate and it could be Trump on the back foot.
There's just over 100 days to go before the election, it is going to be fascinating to follow.
Ultimately I think that the Harris campaign will fall away, but there is no certainty that Trump will win at this point in time. Last week it was a dead cert, now maybe not so much.
They say a week is a long time in politics and we've all just seen how true that saying is.
