Loading JSON object with special values as a string

I'm trying to create a string JSON object to load using the json module; however, I'm having some trouble since some of my values are the python True and False rather than unicode strings. For example, I want do the following:

>>> newDict = json.loads(u'{"firstKey": True, "secondKey": False}')
>>> newDict.get('firstKey') == True
True

but I'm getting:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.6/json/__init__.py", line 307, in loads
    return _default_decoder.decode(s)
  File "/usr/lib64/python2.6/json/decoder.py", line 319, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib64/python2.6/json/decoder.py", line 336, in raw_decode
    obj, end = self._scanner.iterscan(s, **kw).next()
  File "/usr/lib64/python2.6/json/scanner.py", line 55, in iterscan
    rval, next_pos = action(m, context)
  File "/usr/lib64/python2.6/json/decoder.py", line 185, in JSONObject
    raise ValueError(errmsg("Expecting object", s, end))
ValueError: Expecting object: line 1 column 13 (char 13)

and of course if I change the True and False to "True" and "False", my condition is not met either as they are now strings and False would be returned.

Can you use lowercase true and false?

>>> import json
>>> d = {'firstKey': True, 'secondKey': False}
>>> json.dumps(d)
'{"secondKey": false, "firstKey": true}'
>>> s = json.dumps(d)
>>> json.loads(s) == d
True
