I'm not sure TV debates really change people's minds, the participants are coached to deliver sound bites . IMO most people's minds are firmly made up, but a few may be changed by local issues such as the recent flooding.
I am definitely not a "worshipper" of Corbyn, but I do care about our society and how selfish and aggressive things have become, and how many are marginalised, particularly the vulnerable and old.
The Tories will probably win the election, purely on Brexit, and sadly in the future it will be more of the same.
