Actually, no, they didn’t. Margaret Thatcher was well educated, politically savvy, hard as nails, serious, well spoken, and extremely knowledgeable. No, no one said she couldn’t handle the job.
Plenty said she couldn't handle the job. Just not enough to stop her election.
Yet your hero Bums detractors were correct in his inability to handle the job!
Hope you enjoy your crap sandwich as it goes down!
