CNN singles out Dean yet again

The CNN Quickvote poll on their main page right now reads "Should Howard Dean stay in the race until the convention?"  

Why is are they not asking whether the other candidates should be leaving the race?  Dean came out far ahead of both Clark and Edwards in Michigan, and even Kucinich beat them in Maine, but the media doesn't seem interested in calling on either one of them to quit the race.  

If the only ratonal is that they each won a state that the Democrats will likely loose no matter who they run in the general election, it is an even sadder commentary on how the media views this pivotal moment in our country's history.

~sigh~
