She was not booted from caucus for stomping on the GWB doll. It was for her comments she made regarding the Prime Minister later in an interview. I think the stomping would have been ignored (as usual) as just another jab at the american government if that was all she had done.

Prime Minister Paul Martin made the decision Thursday after Parrish's latest outburst, which took direct aim at the Liberal leader and his closest advisers. "I cannot, as leader of our party and the government caucus, tolerate behaviour that demeans and disrespects others," Martin said.
"It is unacceptable."
Parrish's cardinal sin appears to have less to do with her repeated, undiplomatic outbursts against the George W. Bush White House than her comments on the prime minister himself.
"If he loses the next election and he has to resign, I wouldn't shed a tear over it," Parrish said Wednesday in an interview with The Canadian Press.
"I have absolutely no loyalty to this team - none."
Her ejection from Liberal ranks reduces Martin's tenuous minority in the House of Commons to 134 Liberal seats.
The Conservatives hold 99 seats, the Bloc Quebecois 54 and New Democrats 19.
Parrish becomes the second Independent in the Commons.
Parrish's ejection was precipitated by another round of public Bush bashing.
With the president preparing to make his first state visit to Ottawa at the end of the month, Parrish taped a piece with the CBC comedy show This Hour Has 22 Minutes.
In the skit - which is to air Friday but has already appeared on CBC news programs and been requested by some U.S. networks - Parrish stomps a Bush doll under her booted heal.
When fellow parliamentarians, including some Liberals, criticized her behaviour, the veteran MP for Mississauga, Ont., let loose Wednesday.
Parrish said she won't be silenced and that efforts by Martin to do so will backfire.
"After what they've put me through and lots of my colleagues, they can all go to hell," she said. "But he's not going to control me, so all he's going to do is end up looking weak."
