Yes, it’s because of the election, but it’s also because the polls in the swing states show him getting crushed by former President Donald Trump — and specifically show him being crushed on that particular issue.
Not only is he now up in all seven swing states, he’s up by some big numbers in some of those states. Trump is up by eight in Nevada and 10 in North Carolina. Even stunningly up five in Michigan and eight in Georgia.
Collectively, that poll has Biden down six points, 48 – 42 percent, and that’s consistent now with other polls. They also prefer Trump, 51 to 33 percent, on the economy, which is still the single most important issue.
