How can you tell when your presidential campaign is tanking? Well, it might be a hint if your support has dropped so much that voters in your own party are four times as likely to vote for a candidate from another party than for you.
In a poll just released by the University of Iowa, Barack Obama gets almost four times as much support from Republican voters in Iowa as John McCain does, 6.7% to 1.8%. McCain's support was 14.4% in March.
Turns out that among Iowa Republican voters Obama beats every Republican except Romney (21.8%) and Guliani (10%). Not bad for a Dem!
