The candidates now move on to Nevada ahead of Saturday’s caucuses, followed by contests in Colorado, Minnesota and Missouri. Already campaigning in Nevada, former Pennsylvania Senator Rick Santorum cast himself as the most viable “conservative” candidate in the race.

Rick Santorum: “We can’t allow our nominee to be the issue in the campaign. So I say to the people of Nevada—in fact, to the people across this country—if you want a strong-principled conservative who is not going to be the issue in the campaign, who is going to make Barack Obama the issue in this campaign, please vote for me and help us out.”
