Trump's falling approval ratings signal potential shifts in US midterm election outcomes.
Context
What happened: A Reuters/Ipsos poll published Monday shows President Donald Trump's approval at a record low, with more respondents saying they plan to vote for Democrats on November 3.
Key numbers: 31 percent approve of Trump, down from 32 percent two weeks earlier.
Why it matters: Experts say Democrats could flip both chambers, and researchers say the odds Republicans keep their thin majority are very small. NBC News sees possible House flips in 15 districts and likely Senate Democratic wins in North Carolina and Maine.
