Personally, I do not think our lefties get it.
Last night at the Trump "protest" in PA, it was reported there were 15% of the crowd that identified as Democrats. Another 14% have never voted before.
Just 13 days ago an independent poll by Democracy Institute (DI), a nonpartisan polling showed Trump pulling ahead of Biden and winning the Electoral College with 319 votes. This same polling firm accurately predicted the outcome of the 2016 election and Brexit. And in this poll of likely voters they sampled Democrats by 2% more than Republicans.

When you look at RCP averages it is deceiving. All the polls that have been posted from the beginning are averaged in with the new. And even with the averages, Biden is down below the MoE in the polls in battleground states. Today a poll showed Biden just 1+ of Trump in the state of Nevada. There have been numerous polls show Trump doing well with Blacks and Latinos. RCP and the media networks still show Texas as a state in play but Texas inner polling show Trump up +10.
This election has everything to do with the ideology of the Democratic party that has taken a sharp turn left just to attempt to shore up their base. There are certainly Republicans that are the opposite but there are a good number of Independents and Democrats as well that oppose this far left turn in the Democratic party.
