DAMN

Ipos-Reid, which I consider more reliable than the SES tracking poll, puts the Liberals back in the lead in the popular vote, with the Conservatives still holding a moderate lead in the seat count estimates:

As The Final Week Begins, Too Close To Call
Seat Projection Model Suggests Conservatives Take 110-114 Seats, Liberals 107-111, NDP 19-23, Bloc Quebecois 64-68 -- If Vote Held Tomorrow
Conservatives Stumble As Liberals Slip Back Into Lead In Decided Vote
Liberals (34%, Up 5 Points), Conservatives (28%, Down 4 Points), NDP (16%, Unchanged), Green (6%, Down 1 Point) – Bloc Quebecois (53% In Quebec Vs. 23% Liberal)

Among the major shifts over the weekend:
In Ontario the Liberals now lead 42% (up 8 points) to the Conservatives 30% (down 8).
In Atlantic Canada the Conservatives lead 41% (up 19 points) to 37% (down 6 for the Liberals).

The potential for a majority is nil. The potential for a Liberal-NDP alliance, even at the high end of the projections is well below the needed 155 seats.

I'm disappointed to see the Conservatives lose ground, but on the upside things have gotten more interesting.
