  • Democrats enter the final three full months of the campaign season with key advantages in the Senate races that are crucial for the party to win back control of the upper chamber. Between July 25 and August 2, Data for Progress conducted a poll of likely voters in four states--Arizona, North Carolina, Maine, and Iowa--using both web-panels and text-to-web.

In all four races, Democratic Senate candidates lead their Republican opponents. Of note, Republican Senators are running behind President Donald Trump in three states, Arizona, North Carolina, and Iowa. Only in Maine is Republican Susan Collins outperforming Trump.
