what many people want:

do the right thing regardless of political calculation.

Even at the risk of not being relected.  The lure of power becomes so strong, that your point is forgotten by many who rationalize away their original ideals.

You should save this diary so that after you are elected in 2008, you can pull out that statement and look at it, and remember to follow it regardless of electoral consequences.  I bet it actually is politically better to do so, but even if it is not, do it anyway, as best you can.
