Why does the media say HRC won Texas?

I wrote this to CNN.com today ...

Why do news organizations continue to write and report that Hillary Clinton won Texas? True she won the Texas primary, but Barack Obama won the caucuses and ended up with more pledged delegates overall, because his caucus winning margin was more than her primary winning margin.

On March 11, 2008, the following headline ran on CNN.com's Politicalticker blog:
"Caucus win gives Obama more Texas delegates than Clinton."

Yet today (April 23) at 1:21 p.m. CNN's Jack Cafferty posted on Politicalticker:

"Posted: 01:21 PM ET

FROM CNN's Jack Cafferty:

Barack Obama missed another chance last night to knock Hillary Clinton out of the race. He beat her in Iowa, she came back and won New Hampshire. He reeled off eleven wins in a row, she came back and won Ohio and Texas."

I am not accusing CNN of a pro-Clinton bias, but I am curious why CNN's own political blog would propogate this error.

Thank you for your time.
