National Party last election 528,442 votes 3.6% of the population, with a falling youth and female membership.
Declining membership, more scandals like Barnaby ( just the start ) and disgraceful attitude towards women means that the National Party is having a hard time being invited to polite company.
The smarter, more educated people leave. Mostly because they want to escape the need to be like Barnaby to be accepted. Take a good hard look at where the New England is headed.
