I read Barone's Almanac last night, and Issa ran as a pro-lifer right from the start. I don't know why I thought he was pro-choice.
However, I noticed that Issa had a very contentious, mudslinging GOP primary in 2000 for the 49th CD nomination with----State Senator Bill Morrow. So it shouldn't surprise anyone that he would endorse one of Morrow's primary opponents, although why Bilbray and not Kaloogian I have no idea.
Something about Issa has never struck me as quite right, just a gut feeling. I had forgotten that Morrow had been his primary opponent back 6 years ago. There was a lot of bad blood because Issa effectively bought the nomination out from under Morrow (nevermind the sleazy allegations Issa made).
" why Bilbray and not Kaloogian I have no idea."
FWIW on the Hedgecock show a couple days ago, Issa said Bilbray's never shy'd away from tough fights. He admires his guts.
Gonna be a nasty fight these next few months.
