In previous months, it hovered between 44 and 46 percent. Trump's current approval rating is two points higher than what President Barack Obama had in the same poll during the same period in his presidency. Trump's is also at an all-time low, at 49 percent. Pollsters are looking disapproval rateat Trump's favorability as a weather vane for the midterm elections, especially in states where elections are contested. Trump has been traveling the country to campaign for Republican congressional candidates for the past several weeks.
