Is The Express a conservative newspaper?
Yup.
But they have been aroubd since 1927 and have a very solid reputation. In addition, after the newspaper was sold to new owners recently, they are much less conservative than they used to be.
That the Express is conservative is a good thing. But when you’re looking at polls the most important thing is accuracy, not agreement. Though the Democracy Inst (the Express poller) got both Trump’s first election and Brexit right.
It shouldn’t take long to see if there’s a swing back to Trump. Should see further evidence this month if it’s happening.
