A bit of number crunching shows that if an election were held today, the Liberals would make quite a breakthrough.
Here is the Quebec seat distribution in the federal Parliament, as of last October's federal election;
Here are the ridings that the Liberal would take away;
Compton--Stanstead (BQ), Ahuntsic(BQ), Alfred-Pellan(BQ), Brome-Missisquoi(BQ), Brossard--La Prairie(BQ), Gaspésie--Îles-de-la-Madeleine(BQ), Gatineau(BQ), Jeanne-Le Ber(BQ), Laval(BQ), Louis-Hébert(BQ), Haute-Gaspésie--La Mitis(BQ), Outremont(NDP), Pontiac Saint-Lambert(CONS)
Here are the ridings that the BQ woud take away;
Chicoutimi--Le Fjord (CONS)
The following ridings, now held by the Bloc, are in danger of going Liberal should the Liberals increase their polling numbers by just 2% with a commiserate fall in support of the BQ.
Abitibi--Témiscamingue, Compton--Stanstead, Abitibi--Baie-James--Nunavik, Saint-Maurice--Champlain, Shefford
Interestingly, the drop in Conservatives support by over 30%, translates to a loss of only 2 seats.
