mistletoekisses oh yay! a fellow Portillo-adorer! I have loved him since about 1994 I think (when I was in 6th form ) then in about 2000 I actually met him and was (like you) rendered utterly speechless by how charming and magnetic he is. The crush continues to this day.
ANYWAY back to the subject, YANBU to fancy David. Ed not at all my type but my husband has met him a few times (through work) and says he is by far the cleverer and more charming Miliband with more potential as leader. So there you go.
