Oh no.
When you dig down into the details, there are multiple things that don't jive with the polls. ie: In most swing states, there are more registered democrats than republicans. The margin has shrunk in most of those states since 2016. These are states that Trump won in 2016, yet the polls are giving those states to Biden. (I will try to remember to post examples as I come across them) This is just one example. I truly think many of the polls are as corrupt as the media. They are building the narrative that Trump cheated and Russia helped.
Trump has had the goods on Biden, Clinton and Obama since 2017. He will release whatever he needs between now and the election to assure victory, then let Barr deal with the prosecutions.
In 2016 I was busy with life and didn't have time to delve into the details. I was also not a Trump fan and didn't decide to vote for him over Johnson until the last week. I was as surprised as most on election night. This year I have more time to dig into the details. I can certainly be wrong but feel pretty good at the moment.
PS: Regarding extended deadliness to count votes, 6 of 7 circuit courts have sided with the law and not allowed extensions. The democrats were relying on having a set number, in close races to make up like the seven house races they flipped in Orange County after election day, 2018.
