Poll: 52% Prefer Democrat-Controlled Congress

NBC's final poll before Tuesday's midterms has 52% wanting a Democratic-controlled Congress and 45% wanting a Republican one. The Washington Examiner says that margin grew two points since early September, which is inside the poll's 3.1-point margin of error, so the pollsters are about to spend a week explaining a number that barely moved. Trump's approval sits at 40%, against 46% in NBC's last 2018 poll, and 73% of respondents are unhappy with the economy. Around here, a man who counts his cattle every morning learns that a headcount only tells you what was standing in the pen when you counted. Don't count your chickens before they hatch, and remember that a poll is a snapshot, not a sale.
