Probably pretty marginal considering people actually listen to Alex Jones, Ben Shapiro, Paul Joseph Watson, Milo Yiannopoulos, Rush Limbaugh...

Not really, this is basic marketing, everyone you listed has their niche appeal. Alex Jones built his crowd from the hardcore conspiracy niche and has over the top screaming presentation. He elevated himself to viral meme status. Ben Shapiros niche is an ultra-confident fast talking 'logic machine' who is very good at making left wing college students look stupid. Paul Joseph Watson is the classic 'dry humor' condescending british idealouge archetype that americans have always enjoyed. Milo is the flamoyant bitchy gay troll who can double up as a stand up comedian on his tours. Rush Limbaugh is also a flamboyant and extroverted personality (less so than milo or jones) and is helped by the fact he has been around for a LONG time and caught the wave of the always right leaning  talk radio crowd who he's had a long time to appeal to.

Lauren Southern brings absolutely nothing to the table that someone else hasn't done more successfully before her. She doesn't attempt to be funny, she isn't very good in debates, nothing about her demeanor stands out. She's popular because shes a pretty girl with right wing opinions. Sex appeal is all she has.

 I challenge you to 'describe' Lauren Southern's personality to me in a way that might make me or any other men in my age group interested in listening to her if I didn't already know she was a hot 22 year old blonde. If you think Lauren Southern would have the same audience if she was a fat 78 year old balding mexican man you are dreaming. Don't downplay the effect of optics.
