Polls increasingly pointto Democrats winning the Senate.

Why it matters: Republicans had been optimistic about holding on to the Senate even if President Trump lost. But they know they could be swamped by a blue wave.

Maine and Arizona, once tossups, lean Democrat.

• There’s a new poll in Iowa with Republicans down (3 points, within the margin of error).

The context ... Cook Political Report rates six seats as tossups, all held by Republicans: Colorado, Georgia, Iowa, Maine, Montana and North Carolina.

• As a seat that's trending their way, Republicans point to Sen. Thom Tillis (N.C.), and say he bested challenger Cal Cunningham last week in their first televised debate.

The bottom line: Almost every competitive race looks shaky for Republicans.

• And Democrats are raising gobs of money after the death of Justice Ruth Bader Ginsburg.
