Bitter Clingers And Single Cat Women

When Barack Obama said:

"They get bitter, they cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations."

How was it different from J.D. Vance saying these things?

“a bunch of childless cat ladies who are miserable at their own lives and the choices that they've made and so they want to make the rest of the country miserable too.”

“Look at Kamala Harris, Pete Buttigieg, AOC—the entire future of the Democrats is controlled by people without children.”

I think they're basically the same:  They are appealing to their base.  Obama knew he was never going to get the bitter clinger vote, just as Vance knows he isn't getting the single cat lady vote.  Lot's of people acting all hurt over this, but let's face it, you were never going to vote for him, no matter what he said.

Added: Let's assume these quotes weren't mistakes in an unguarded moment, because then they mean nothing:  Everybody says stupid things from time to time.  Which of these could be more likely to appeal to swing voters?  I think Vance's win by a lot, here's why.  Married women with kids are the quintessential swing vote.  They're slightly Republican, but only slightly.  Their votes can be won or lost and they're a huge demographic.  On the other side, is there a big swing demographic of people who are anti-religion and anti-gun?  I don't think so.  I think they're massively Democratic voters and not really winnable or losable. 

Added: Two other major differences:  Obama was the candidate for president and Vance is vying for VP.  Obama made his comments on the campaign trail and Vance made his comments three years before being chosen as Trump's VP.
