Will there really be a reelection? Still I think not much will change to the better if the CDU wins (whether Merkel, Stoiber, or Hessen-H. Koch will be chancellor; OK Stoiber and Koch are worse). What's really bad is that they would obtain the majority in both chambers! Although the situation of now with SPD/Greens having a majority in the Federal Diet and the CDU/FDP having one in the Federal Council leads more often to some kind of blockade, they nevertheless have to make compromises, which I think is better than controlling the complete legislature alone.
As I see it today CDU will win in autumn (I just can't imagine anything different). The only problem they have now is, they have to find a “good” candidate for chancellor. I don't think Stoiber is electable in Germany (who else but the Bavarians would like him as chancellor?), Koch of Hessen is even worse (he has got a not-so-nice nickname: Hessen-H.; I even won't write out the H. because I don't want some kind of keyword(s) to find my site) and then there's Mrs. Merkel; well I'd like to see a woman being chancellor, be assured, but Mrs. Merkel?
So there's just to hope that the economy party FDP (party of well-to-do; they call themself still “liberal”) won't do the 5% this time…
