There’s a lot of work to be done, but polling is looking promising for a Democratic takeover of the Senate.

As more state polls are released, it appears that few Republican senate seats are completely out of reach. For example: While GOP candidates are ahead in Iowa and Missouri, it’s not by much — and these races weren’t supposed to be competitive.

No one expected North Carolina to be a race, but Democrat Deborah Ross is now leading incumbent Republican Richard Burr by two points. That’s significant.

One reason is that we’re seeing moderates flock to Hillary Clinton in every state — and there’s a direct correlation between presidential and Senate choices.

In Iowa, a state Republicans thought was safe, the race is tightening. Chuck Grassley, a prominent Trump supporter, is ahead of Patty Judge by 7 points when he was expected to easily defeat his challenger. While Judge may not win, that means the RNC now has to defend Grassley’s seat.

Missouri (also thought to be out of reach) is now competitive. Sen. Roy Blunt is only 3-4 points ahead of Democrat Jason Kander, who is steadily gaining on the incumbent.

In Indiana, in the race for a Senate seat left open by the retirement of Sen. Dan Coats, Democrat Evan Bayh maintains an 18-point lead over Republican Rep. Todd Young, 54-36.

Even in states where Democrats may not win, tightening polls will compel Republicans to spend money defending what were supposed to be safe states.

Although numbers can (and will) keep shifting, a Democratic takeover of the Senate looks increasingly possible.
