Yes, incumbents usually have an advantage. They usually are more popular than Donald J. Trump though.

Yes, Republicans have some institutional advantages in their efforts to hang onto the House. But they only help so much in a wave election.

There are many things Democrats need to take back the House next year. One they don’t yet have is abundant GOP retirements.

The idea that there is a “law” that says Clinton will lose for that reason is belied by history.
