Like it ever existed in the first place.
The Blue Wave was a joint creation of the Democrat Party and its allies in "communications", which is to say it was manufactured out of whole cloth for anyone who still happened to turn on the TV or the radio to get "the news". The number one objective? Demoralize the electorate which made Trump president. The polling operations funded by the Democrat media provided "proof". Like the cell phone towers which litter the American landscape, their websites became the online repeaters of this "information".
The point of this propaganda was to create the wave, not report on it.
Some polling operations were more honest, or stumbled into the truth.
Rasmussen has had the race tied twice, as far back as mid-August and also in early October (Christine Blasey Ford testified and Brett Kavanaugh defended himself on September 27th, flipping the poll from Dems +5 to Tied by October 4th).
Investors Business Daily had the race tied already in late July.
Rasmussen has had the race as close as Democrats +1 way back in May.
So did Reuters/Ipsos.
Just remember folks. For every 108 members of Communications faculties in America's colleges and universities, there are exactly ZERO registered Republicans among them.
Just about everyone you listen to in this country for information, from the time you're in kindergarten all the way to the retirement home, is a registered Democrat, or was "informed" by one.
Steve Liesman, here, getting out in front of the lies to burnish CNBC's credibility:
The latest CNBC All-America Economic Survey offers mixed signals, but leans against a wave Democratic election like ... those that swept Republicans to power in 2010 and 2014. ... "A six point differential is not something that's going to cause a big electoral wave," said Micah Roberts, the Republican pollster on the CNBC poll, a partner Public Opinion Strategies. "Economic confidence that people have among a lot of groups is providing a buffer" for Republicans. ... Jay Campbell, the Democratic pollster for the survey and a partner with Hart Research Associates, is skeptical of a wave for the Democrats, saying the six-point advantage is "not enough to suggest this is going to be a massive wave election a la 2010." Campbell did add that the survey found a large 17 percent of undecided voters who will be critical to the outcome.
