While a majority of Democratic and Democratic-leaning voters (53%) favor a so-called "Dream Ticket," fully 54% of Obama supporters do not want Clinton chosen as his running mate.
While Obama has opened up a wide lead in the Democratic primary, he now runs about even against McCain. The tightening general election shows some sullying of Obama's personal image over the past three months, which is in some measure a negative reaction from frustrated Clinton supporters. McCain's image has also become more negative since February, however, unlike Obama, those who disapprove cite his political beliefs.
Barack Obama's 'bitter' comment registered widely but just 29% of Americans say they paid very close attention to news about the presidential campaign last week, the lowest percentage recorded since December 2007.
About two-in-five voters now say they have received a pre-recorded call about the campaign. Meanwhile, Democrats are far more engaged in campaign activities than are Republcians -- including donating money to a candidate.
Obama's personal image remains more favorable than Clinton's - and he retains a 10-point advantage over her in the race for the nomination. But certain beliefs and attitudes among older, white, working-class Democrats are associated with his lower levels of support among this group.
The public remains highly engaged in the election, with no increase in campaign fatigue. Also, with the Democratic race still in question, a Gore endorsement would be more influential than one from Edwards.
Republicans and Democrats agree the economy should be a top priority for the president and Congress, but they differ more than ever on the importance of other domestic issues -- such as global warming and health insurance for the uninsured.
The internet is living up to its potential as a major source for news about the presidential races. Nearly a quarter of Americans say they regularly learn something about the campaign from the internet, almost double the percentage at a comparable point in 2004.
