for sure.

I guess both! I guess he can´t choose wich one he loves more!

I picked Dean because of the episode Dream a little Dream of me. I felt a strong connection between Dean and Bobby.

I can't recall off the top of my head any time that Sam and Bobby have had a meaningful conversation, whereas Dean and Bobby talk all the time. Not that Bobby doesn't love Sam, I just think he connects more to Dean. But I've thought for a long time that Sam has a harder time making genuine connections with people than Dean does.

of course Bobby loves them both but he's closer to Dean and I think he consider him the son he didn't have

I think he talks to Dean more, but he bonds with Sam over books and he's the one Sam calls for help. I have also realised they have this silent communication thing going on- yeah, telepathy, dummy!- like in Yellow Fever, and in When the Levee Breaks, Sam's might be more emotional, but is just not as needy as Dean.

Yes, I said it, Dean needs to have things explained to him so he realises that he's not Atlas and has to carry the weight of the world on those delicious, broad, brawny, tanned, tight shoulders of his.

Dean is there for Sam, but Bobby is there for both.

Pretty sure on this one (:
But of course he loves both

I think he loves both, but between him and Dean is a better relationship...

i always thought Bobby loves Dean more.

I voted for Dean. I have no doubt that Bobby loves them equally, I think he's closer to Dean mostly because he's so like John in many ways.

^^^agree with above. i think he loves them both equally but has a closer relationship with dean
