You are exactly right. The wave has been growing and there is a major effort underway to squelch the Conservative voter enthusiasm (by the Media) from some partisan pollsters.
These partisan pollsters pull the same garbage over and over.
You are right about that. Every time about a week or two before an election the polls coming out, especially by the liberal media, showing a tightening of the races. This is done in order to keep voters energized and increase turnout. If every poll showed one candidate up by 10 points it would dampen enthusiasm and turnout. These polls are nonsense and even more so in states where early voting is going on. It was reported this week that early voting and absentee ballots are overwhelmingly showing a Republican tsunami on the way.
