The governor was asked if he will run for president in 2016 and while he never said yes - he also never ruled it out.
Nixon says he's focused on what he can get accomplished as governor before his term ends.
Political science experts say the governor may be positioning himself to be more visible on a national level -- something he'll need to do if he wants to make a run for the White House.
"He just made the pronouncement recently about how he believes the same-sex marriage ban in Missouri ought to be lifted," said MWSU Political Science Professor Melinda Kovacs. "I think what we see on a more local and regional level is an increasing sharpening of the contrast between Missouri and Kansas right next door and I think that there's a lot of that that goes into making Governor Nixon more visible, more noticeable and possibly more known on a national stage."
Nixon cannot seek a third term in 2016.
