Interestingly, in the first election in Scotland after Thatcher won power in the UK, the European Parliament elections, Thatcher won more votes than any other party. She even managed to win more votes than Labour and won 5 of the 8 seats on offer.
Her 33.7% share of the vote suggests that she wasn’t that unpopular in Scotland.
By the time of her last general election victory, Thatcher’s share of the vote stood at a very respectable 24%. In the following general election, under John Major, the Conservatives won 25.6% of the vote.
Margaret Thatcher was popular in Scotland with a sizeable proportion of the electorate. She was far more popular than the SNP.
