Would a Obama/Clinton ticket have done better or worst

[Pres Mike]

Some stories say that Obama offered either VP or SoS to Hillary for her endorsement and support.

Suppose Hillary was offered VP and accepted. What does the general election look like?

According to the post 2008 NBC poll, 16% of McCain voters would have voted for Hillary had she been the nominee

Thats about 9,500,000 votes.

59% of Democrats wanted Hillary as VP

And about 15% of Hillary primary voters voted for McCain in the general election. (For reference, only 12% of Sanders primary voters voted for Trump in the general election)

So, do the Democrats do better or worst? Conventional logic say they do better. 10 million extra votes nation wide probably flips Missouri and Montana. Possibly Georgia and South Dakota

On the flip side, that might be too much for certain people and they vote McCain

On balance, worse. One of the credible attacks against Obama was the "experience" factor and Biden being on the ticket certainly helped in that department. Hillary at that point had only been a senator for 1 term and arguably only got there in the first place because she was Bill Clinton's wife. Also, rightly or wrongly, a lot of people saw Hillary as divisive, you can call Biden many things but divisive wasn't one of them.

Agreed - I was going to concur with the OP on his assessment, but reading your post made me rethink some of the drawbacks to Hillary in the no. 2 spot. Even 2008 Hillary was highly controversial among Republicans, imo much more so than Obama was at that point in time. Biden, otoh, was likeable and inoffensive, and he did bring decades of political experience to the table.
