Minnesota Senate Minority Leader Dick Day, R-Owatonna, broke ranks with Gov. Tim Pawlenty in two significant ways in recent weeks. Last week Day proposed a nickel-a-gallon gas tax hike to pay for transportation projects, which would violate Pawlenty's staunch no-new-taxes pledge. Day has also rejected the governor's plan for a new metro-area casino, favoring expanded gambling at Canterbury Park racetrack in Shakopee.
