I don't think Kaiden is any more or less popular than any other character in Mass Effect. Sure he wasn't one of my favorites but clearly others did like him, as a poster on Bioware social network I know this for a fact. He is perhaps popular among girl gamers because, as people point out, he is a male LI that wasn't an alien but rather just an ordinary guy.

EDIT: And can someone explain how it's possible to like Ashley? She's such a xenophobic *****.
Oh boy, another one of these. Let me start with the basics.
Ashley is not xenophobic, nor is she racist. Her prejudice against aliens is not based on a superiority complex or irrational fear or hatred of the unknown. Her Grandfather fought in the First Contact War and during that time he was forced to surrender to the Turians making him the first human ever to surrender to an alien race.
Thus her family name is blacklisted in Alliance military and she feels she has to redeem her family name but due to the bias against her name she is reduced to small groundside assignments and has gotten no experience with any alien races and has nothing to go on save for the history of the First Contact War.
That is why she distrusts aliens.
That said, on Virmire she still happily volunteers to work with the Salarian team and if she is picked for the job it's clear from the radio chatter that she is perfectly comfortable working with, and possibly leading, a team made up entirely of aliens.
She also mentions at one point to Tali (elevator conversation) that she heard some humans are blaming the Quarians about Eden Prime and furthermore expresses her hope that Tali helping them find Saren will help give Quarians in general a better reputation.
Also after Liara's mother dies on Noveria if you go and talk to Ashley she suggests to Shepard to go talk to Dr. T'soni because she just lost her mum and 'that's gotta hurt'.
She also despises Terra Firma passionately and refuses to have anything to do with them believing that whatever noble goals they may once have had haven now been replaced by simple racism.
Also she herself announces very clearly at one point that she doesn't believe humanity is superior.
Finally, she can be convinced to move past her former trust issues with Aliens and admit to herself that it wasn't the Council or Turians who blacklisted her family name, it was the Alliance. And that while there exist alien foreign powers who do oppose humanity they also don't seem to want to destroy humanity either so this is an opportunity to learn.
As for why people can like her? Well because she feels very believable for one thing. She's tough and aggressive certainly but she also demonstrates a compassionate side to her. She's funny and attractive without feeling like she was designed to be oggled over and the flaws make for good characterization.
