Obviously both are important and ideally would align. But in the real world...
Our local MP is useless. But to be better illustrate my question, we have a really solid MSP here, who has been great at standing up for us, including against their own (governing) party. I would vote for them on this basis regardless of my views on this party. But I couldn't stretch it to Tory, even if they were the best person for the job.
So where's the line? How important is your local MP vs voting for the party you want?
