Wow... I missed a lot haha.
Ok, lets clear a few things up.
If Clinton gets the nomination, she is a better match-up against McCain. The problem with any national polls at this time is that:
1) No Democratic Nominee
2) No VP's
I will agree that Arkansas would be a "swing state" if Clinton was the nominee.
The Problem with Obama is that he can not win the swing states that Hillary has won. We can see this by the large amounts of voters who voted against Hillary (who is supposedly "out" of the race) in those states. According to exit polls (which polled actual voters) a good amount of Hillary voters will not vote for Obama (especially in swing states) and a number of voters will not vote for Clinton. This poses a problem for the Democrats in November. Now this could change with a VP selection, but I can't see a Clinton/Obama or Obama/Clinton ticket.
Obama will take an electoral beating in the General Election in states that he needs to win (Penn, W. Virginia, Ohio) as well as possible losses in New Mexico and New Hampshire. The polls are often skewed by the liberal media who takes them. The reality is simple: Democrats can't beat a Moderate who shares values of both sides. Even though I am part of the base of the Republican Party (True Conservative), and even though McCain's nomination alienates the base, I do know that the Moderate section of the party, the independents, and the TRUE (now considered moderate) Democrats will turn away from the ultra-liberals and vote for McCain. He shares values that moderate democrats and other centrists share.
Let's also remember that the Democratic Primaries are not over yet, and even if Florida and Michigan are counted the way they voted, NEITHER of them will have the EITHER magic number needed to clinch the nomination. Then the back-room deals begin. Cases for why each candidate is better than the other, etc.
Let's not get haughty and say this is over, because its not.
