Rasmussen surveyed Kansas voters on a possible Obama/Sebelius ticket and the results aren't all that encouraging for the governor:

Kansas Governor Kathleen Sebelius has been mentioned as a possible running mate for Barack Obama's campaign. The survey found that just 34% of voters see this outcome as likely, while 53% consider it unlikely. If the governor is selected as Obama's VP, 28% of Kansas voters say they would be more likely to vote for Obama, while 35% say they would be less likely to do so.
