I think they will get in with a large majority, though the polls will tighten. Tactical voting will play a part, and with their policies the Tories have increased political engagement among younger voters - they are ANGRY. I'm not sure it will be a 1997 style landslide, but equally I wouldn't rule that out either.
I live in Suffolk, which is very Tory indeed, and people here are angry too. Some will not vote, some will vote Reform and split the Conservative vote. Some will remain loyal.
Recent polling shows that the Tories have now even lost their lead among voters over 70.
