(CNN) – Sens. Barack Obama and John McCain will win in Wisconsin, CNN projects.
Sen. John McCain is looking to pick up more delegates as he inches toward his party's nomination.
The victory marks the ninth consecutive win for Obama over rival Hillary Clinton since a split-decision on Super Tuesday two weeks ago.
"The change we seek is still months and miles away," Obama said Tuesday night in Houston, Texas.
"It is going to take more than big rallies. It is going to require more than rousing speeches ... it is going to require something more because the problem that we face in America today is not the lack of good ideas. It's that Washington has become a place where good ideas go to die," he said.
Obama and Clinton have turned their attention to Ohio and Texas, which hold contests on March 4. Early voting began in Texas on Tuesday.
In the Republican race, Wisconsin gives McCain at least 13 more delegates; 24 more delegates are to be awarded to the winner of each congressional district.
The remaining three GOP delegates are unpledged Republican National Committee members.
As Obama has emerged as the front-runner in the Democratic race, McCain has increasingly directed criticism toward him.
"I will fight every moment of every day in this campaign to make sure Americans are not deceived by an eloquent but empty call for change," McCain told supporters Tuesday night.
