GOP seat lead shrinks as Biden approval ticks up — CBS News Battleground Tracker poll

Republicans head into the fall still in position to gain enough House seats for a majority, but a tumultuous summer has made their advantage appear a little smaller today — with a trend so far pointing toward narrow gains instead of a wave. Our CBS News Battleground Tracker estimates Republicans at 226 seats today, down from 230 estimated in July. A majority of 218 is needed to win control.
