At least part of the reason that there's no difference there is that the
're' module was imported in both cases:
C:\Python27>python -c "import sys; print('re' in sys.modules)"
True
C:\Python32>python -c "import sys; print('re' in sys.modules)"
True
Steven is right to assert that there's a cost to loading it, but unless you
jump through hoops it's not a cost you can avoid paying and still use
Python.
