In a tweet, the president mocked reports of Democratic Party strength heading into the midterm elections, predicting a "Red Wave" of GOP victories instead.


"Great night for Republicans! Congratulations to John Cox on a really big number in California. He can win. Even Fake News CNN said the Trump impact was really big, much bigger than they ever thought possible. So much for the big Blue Wave, it may be a big Red Wave. Working hard!" Trump tweeted.

Trump's tweet comes hours after businessman John Cox (R) secured a runoff slot against Lt. Gov. Gavin Newsom (D) in Tuesday's primary.

Democrats secured their own victories Tuesday night, however, scoring at least second-place finishes in every race they targeted.

California is home to 10 of the most competitive House races this November, as Democrats try to overcome a 23-seat deficit and retake control of the lower chamber. The latest CBS News–YouGov Battleground Tracker shows the Democrats with a slight advantage over Republicans currently for control of the House, well within the poll's margin of error.
