… in the local elections, are you looking at local councillors and deciding which one would be best fit for your area, or are you looking at MPs and central govt to decide who gets your vote?
IABU - using central govt and MPs to decide who to vote for (effectively a protest vote)
YANBU - using local councillors and local issues to decide who to vote for
[No local elections in my area but if there were I would look at local councillors and issues to decide)
