So why call an election she knows will subject her to brexit questioning, especially when she says she called it to seek a brexit mandate, if she doesn't want to talk about brexit. Makes no sense.
To secure the conditions at Westminster that will allow her to mitigate the risks and issues she has faced in recent months.
She will have been advised that there will be a lot of 'noise' about debates etc. but also that if she and all her core team, just weather that for a while and say as near to nothing as possible - it will not amount to anything that will stop her increasing her controls in terms of seats and timeline.
I know it will cause a lot of people a lot of frustration - but it makes perfect sense.
