*Energy sector drops 2.7 percent as oil slides

TORONTO, Oct 1 (Reuters) - The Toronto Stock Exchange's main index ended lower on Wednesday, pressured by economic worries and weakening oil prices, but it finished well off its morning lows on optimism that U.S. lawmakers will push through a revamped rescue plan for the financial sector.
Continuing oil price volatility pulled energy shares to a 2.7 percent loss as the price of crude fell below $100 a barrel, but the key financial and materials sectors largely held their ground ahead of a U.S. Senate vote on the rescue plan expected later on Wednesday.
"People certainly feel that something's going to go through. Whether it goes through today, tonight, tomorrow or Friday is anyone's guess," said Bruce Latimer, a trader at Dundee Securities.
The S&P/TSX composite index .GSPTSE ended the session down 38.39 points, or 0.33 percent, at 11,714.51, a sharp improvement from its 200-point dive at midmorning.
