Fighting in Pennsylvania

Unfortunately, it seems that we are once again seeing the Democratic presidential candidates battle it out. While we seem to have had some sort of relative lull recently, the Pennsylvania primaries have rekindled the debates. The change was apparent when the candidates went from saying that their respective opponent could beat McCain in a general election to apparently now saying that the other couldn’t win in the general election. But that’s just one small example of the fighting going on. Essentially the real problem is the fact that neither Obama nor Clinton seems to be able to go one day without verbally attacking the other.
Now, maybe this is very naive of me, but I was honestly hoping that we might have a cleaner run for the presidential candidate this year. Instead, it seems like McCain is just having some sort of relaxing nap while the Democratic candidates tear each other to pieces. I just find this strange because it seems like both candidates have similar ideas, at least for the most part. And when these primaries and caucuses first began, there were many people who found that they liked more than one of the candidates. But now we have negative ads coming through the mail and showing up on the T.V. and it seems like half of the debate time is eaten up by issues that really don’t matter (read: Obama’s old pastor and Clinton’s Bosnia incident). Granted, this has been happening for a while now, but why? Both of the candidates know that the longer this goes on, the worse things are going to be when one of them is running for president.
I guess the part that really concerns me is the large possibility that neither of the candidates will be able to have the minimum of 2,025 delegates needed to win. I mean, if this is the fighting we must put up with at a big primary, just think of the convention. I have a feeling that the unity they’re hoping for after convention will be elusive.
