You're just using a single, specific incident and trying to draw parallels to a whole group, which is something you do all the time.
It's just a stupid way to make a point.
I don't have an example of a Democrat mimicking exactly what you described, but have plenty of examples of them backtracking, being hypocrites, and capitalizing on misfortune or shitty behavior to succeed.
A single specific incident
Vance made these kinds of comments many many times
Maybe you'd prefer to hear from Rafael Cruz, Lindsey Graham, Mitch McConnell, Kevin McCarthy, Nimrata Haley or Elise Stefanik
Those are just a few off the top of my head that have had very harsh comments about THE TRAITOR only to come begging for his endorsement. I'm not talking just the usual disagreements about policy. I'm talking about personal attacks on him, his character, etc...
I've already posted videos or quotes from most of the poeple listed above
Here is a link to what Stefanik used to say about Trump. I'm guessing you might have forgotten this or never even knew it:
