Converts often become the most fervent believers/supporters

[Stinky The Clown]

(Note the word "often", which different from the word "always".)

I suspect this phenomenon is often so because, almost by definition, conversion is a choice.

Religious converts often become fervent believers.

People leading sedentary lives often become running addicts when they take it up, even late in life.

Devotees of one cuisine or another frequently become skilled at preparing it after visiting the country or region.

And so it may well prove true that people who abandoned Trump to vote for a Democrat in 2018 will stick with the Democrats in 2020 and beyond. People chose, for example, Abigail Spanberger in VA-7 to assume a long held Republican seat (about 50 years). As of today, she again holds a slight lead, with rating organizations calling it tossup or lean Democratic. Those are converts continuing to be supporters.

Anecdotally, how many of us can cite incident after conversation after second hand story of long-time Republicans choosing the Democrats this cycle, much as they did in 2018 or even for the first time now.

These converts can become stalwart Democrats if they are welcomed and nurtured. Keep in mind, they came here knowing full well who and what WE are. And they chose to vote with us.

1. "knowing full well who and what WE are" - not completely accurate.

They have had their heads filled with nonsense for decades; it will take them a long time to purge the Fux Noise from their minds and see us for who we really are. We will have to help them do that.

4. And we also must remember...

that if they've found their way to us in the first place, that can be a good indication (though obviously not always) that they have already recognized a substantial portion of the Fux Noise. I myself am such a convert, having changed stripes in the middle of the first term of the Bush 43 administration.

It is also in our interest to remember that for MANY of these people, it's not necessarily actually a conversion.
It's an AWAKENING to the fact that they always have been aligned with Democrats.

Speaking for myself, anyway, I did not change what I believe in and support.
I merely finally recognized that Republicans were LYING about standing for what I believe in and support.

I realize, of course, that there are those who genuinely do oppose what Democrats actually stand for, and the reasonable caution with which such prospective "allies" should be regarded, but those are a VERY different class of people from those who merely oppose what they'd been manipulated into thinking Democrats stand for, not what we actually do.

I'll harken once again back to Secretary Clinton, in the oft-overlooked paragraph immediately following the "deplorables" comment, where she herself made this exact point.

2. There are a lot of people we will need to welcome back into the fold

We need to get across the message that they were conned by one of the best in the business, they should just admit it cut their losses and move on. We need to resist the urge to rub their noses in it. We will never become the United States again unless we do.
