Boulet is the current Member of National Assembly for the Quebec riding of Laviolette in the Mauricie region.

Boulet was a Liberal candidate for the federal riding of Champlain in the 2000 elections but lost by 15 votes to the Bloc Québécois.

She was the only Liberal MNA to be re-elected in 2007 in the Mauricie region as the ADQ won the remaining seats.

As Minister of Transportation, she introduced legislation related to road safety including the use of hand-held phones, lowering the legal blood alcohol level (for driving) to 0.5 milligrams per litre and tougher penalties for offences such as drunk driving.

[1] However, both the Parti Québécois and the Action democratique du Quebec, which formed a majority opposition, did not support the legislation regarding the blood alcohol level limit and thus will remain at 0.8 milligrams per litre.
