This poll number is very ominous for Democrats

On the eve of his one-year anniversary in office, President Joe Biden finds himself at the lowest polling point of his tenure -- a worrisome omen for Democrats desperately trying to hold onto their House and Senate majorities this fall.

That's according to new poll numbers from Gallup that peg Biden's approval at just 40% with 56% disapproving. It's the lowest measure so far by Gallup and well below his 48.9% polling average over the past year in the organization's surveys. At this one-year mark, that average is about where Bill Clinton was and ten points better than Donald Trump, but that's a very small on-the-bright-side note.

Those numbers are broadly consistent with CNN's poll of polls, which averages the last four national polls to give a better (and broader) sense of where Biden stands. As of last week, Biden approval in the poll of polls was 42% with 53% disapproving.
