It is apparently a common term. NY Times, DailyKos, Stu Rothenberg, Rush, HuffPo, Daily Caller all have used it in various years from at least 2009.
It’s a poli sci term used after the 1984 Republican landslide which aptly describes what happened then and what is likely to happen again this cycle. The status quo is churned up by a huge wave of anti-ruling party sentiment. The signs are all there that a big wave is coming. Confidence in the current administration has been ebbing.
The economy is still crappy despite the government’s spin otherwise, the Precedent is seen as inept, disengaged, and a liar. His policies are anti-capitalist, anti-American and just another attempt at making the US a socialist utopia. So, rather than have a banana republic revolt, the voters will turn-out in November and figuratively shoot them to get things changed. When the wave crashes ashore the beachscape will have been changed dramatically. And thus the analogy to a wave.
If the wave hasn’t changed much after the election then we may have to act with a series of waves of our individual making.
Rush is the only one that looks familiar. I did not pick up on his use of the word.
