Idealistic Pragmatist has got it goin' on.
Chief among the blatant falsehoods Liberal partisans tell each other (and unfortunately the media) is that "the NDP only attacks Liberals ... not Harper."
IP's challenge to Liberals is simple: put up or shut up.
Perhaps Liberals FEEL that it's true, just because after ignoring it for so long, they are super-sensitive to any attack on their atrophied left.
Or maybe because Jack Layton's attacks on their failures on poverty, tuition, child care and the environment echo precisely what their conscience tells them about 13 years of implementing the Reform/Canadian Alliance/Conservative agenda.
But hurt feelings and a nagging subconscious aren't evidence. They are, well, personal. And may be the kind of thing Liberals should be talking to these people about.
And hey, while you're at it, it might be a good time to bring up that victim complex too.
