I have been trying to find the answer for this but i couldn't because i see Haley as a 'fan' of both because:
-in season 1 she supported Lucas and Brooke and got mad when she found out Luke was sneaking out with Peyton
-in season 3 she always tried to help Lucas with 'truly' being with Brooke(masquared party, and after Keith dies Luke gives to Haley the predictions saying they won't become true now without Keith but Haley says 'Look at the first one on your list:Try again with Brooke'.
Then again she supports LP
-in season 5 when Luke tells Peyton he hates her , Haley showed Peyton all the predictions
-she was their minister
But i would want to know what you think , which couple she supports more ?

Overall I think she´s been more pro LP, in seasons 1,4,5(after she realised Lucas was still in love with Peyton) and 6

I think Haley mainly just wants Lucas to be happy.

I think she's supported lucas in whatever he does. she's mostly a supporter of lucas/happiness, like everyone has said.

Like everyone said Haley always supported Lucas with whoever he was happy with!

Yeah, Haley is just a supporter of team "Happy Friends" lol. She just wants her friends to be happy. So whatever her friends want, she wants for them.

However, I think we've seen her be MUCH more pro-LP than pro-BL. Yes, she made a few pro-BL comments in the high school years... but we have like two whole seasons worth of her being team LP. So if I had to pick... definitely LP!

"or even my friend Brooke!" <33

team Brucas + Haley = FTMFW.

She usually supports the person Lucas is with but she even supported LP when Lucas was with Lindey "You can´t marry Lindsey", "I think you wrote that book bacuse you´re still in love with Peyton" And in season 1 she was a Leyton supporter when she found out Lucas hooked up with Brooke. Of course she was against cheating later in the season but she was a LP'er fos sure. Not to mention seasons 4 and 6, So there´s really no contest here.

how can anyone honestly be picking BL? yes, she has supported both at one point or another. but we have seen her be wayyyyy more pro LP than pro BL....

By far

I think Haley's a major supporter of all three people; Lucas, Peyton & Brooke the most!

Haley hasn't ever really supported one couple or another. She's always supported Lucas. Her reactions were based on behaviors of Luke's and what she thought he wanted most at that time. I think she was angry about his sneaking around with peyton in s1 because of the action itself, not because she'd rather see him with brooke. In season 3 she was supportive of him and brooke because it seemed to be what he wanted. After she realized that it was Peyton he really wanted to be with she's been supportive of lp because it's what luke wants.

Definitely even though she's more of a "Lucas supporter" But I think she has just done more to support LP... Well... idk I just always saw her as an LP-er lol

Oh c'mon, this is easy. When Lucas was with Brooke she defiently was a Lucas supporter but with Peyton she was an LPer.

Whoever makes Lucas happy, which both girls did at certain times, look how supportive she was of Brucas in season 3, and Leyton in season 6, she isn't for one couple or the other, her concern is for her best friend!

Of all people in TH who are Leytoners I can't see Haley among those. I see Haley on Lucas side, regardless of the girl. She always looks at his interests and actually I see her more of a BRUCAS fan or better yet not on Peyton's side.
1. In S1, when she found Lucas kissing Peyton in the library she defended Brooke.
2. In 4x08, when Lucas tells Haley he is going to the banquet with Brooke, Haley response was: "I think you guys were good together"
3. When Brooke tells Haley that Peyton & Lucas are together in 4x03. Brooke says: "You are either on team Brooke or team Peyton". When she discovers Lucas is spending time with Peyton, Haley did a strange face and Brooke said,'Welcome to Team Brooke'
4. At the party in 4x03, Haley tells Lucas: "Luke, that's the dumbest thing you've done since the first time you kissed her"
5. Haley, all giggling tells Peyton "I'm gonna be HER matron of honor" referring to Lindsey's wedding with Lucas. Not what a friend and an LP supporter would do.
6. At the rivercourt, when Lucas found Peyton's Cure lyrics and calls Haley she doesn't say anything nice about Peyton but actually tells him to choose one.

And the list goes on and on. Seriously I love Haley but she isn't exactly the biggest LP supporter. There are many Leytoners around: Skills, Karen, Lindsey, Keith, Nathan but definitely not Haley, she is more a Lucas supporter.
