I can appreciate your positive attitude, but I believe you will be wrong about the latter. And I don't think it will even be close. For example, I see little reason why the GOP takes back any of the House seats stolen by the DEMs in 2018 in California.
The GOP has a sizeable seat deficit to overcome. The massive voter fraud coming in November, which some worry will be used to defeat Trump, is much more likely to help the DEMs keep the House and retake the Senate.
You hope
As usual
