Here is an article I bookmarked from last year, detailing the GOP emphasis on GOTV dating to 2001.

That plan, dubbed "72 Hour Task Force," is widely credited with partly helping win control of the Senate and expand their House majority. It will be improved and expanded upon for President Bush's 2004 re-election bid, which is being managed by former White House Political Director Ken Mehlman and generally overseen by Karl Rove.
"The 2002 Republican GOTV effort succeeded in beating Democrats at their own game. Labor unions had become experts in turning out their members and supporters on Election Day to vote for Democratic candidates, said Hazelwood. According to her research, in the 1998 and 2000 elections, union households over performed in turnout results by up to 40 percent, while turnout results among religious conservatives--who often vote Republican-- were found to be under performing.
"To counter that trend, in 2001 Hazelwood, Rove and Mehlman used the Virginia and New Jersey gubernatorial elections, along with several special congressional elections, to test what turnout methods really worked. Even though Republicans lost the governor-ships of Virginia and New Jersey that year, the data they collected was invaluable in calculating a grassroots strategy that led to the big Republican congressional victories of 2002.
"One part of the strategy was to survey voters who voted only in presidential elections and to encourage them to vote Republican in off-year elections. This involved a healthy dose of salesmanship."
