"The fact that you have leaders out there working to put in front of the public the opportunity in those areas is a good public policy piece," Nixon said Monday, Sept. 21, at a news conference outside his mansion.
Nixon noted there are proposals to boost the cigarette tax. One would boost funding for transportation and another for early childhood health and education.
While offering support for initiating the ideas, Nixon held off from a formal endorsement.
"I think there are a lot of miles between now and who gathers all of the signatures," Nixon said.
"As for me putting my finger down on which one of those, I want to wait and see which ones get through the process."
Last year, Missouri voters rejected a sales tax increase for transportation. In the spring, an effort in the Senate for a smaller transportation tax hike won the governor's support for continuing, but the idea died in the legislature.
A cigarette tax increase for education narrowly was defeated in 2012.
