Does Lon Johnson want to expand Obamacare?

Now that Democrats are running to the left on health care thanks to the rise of socialist Bernie Sanders, what does MI-01 candidate Lon Johnson think?

Sanders won his primary against Hillary Clinton in MI-01, 59% to 38%.  Since Lon Johnson’s Democratic base is feelin’ the Bern, will Johnson join them in embracing an expansion of Obamacare?  Or will Johnson turn his back on his Democratic base by standing with Hillary, who thinks Obamacare is working?

NRCC Comment: “Voters in Michigan’s First District deserve to know if Lon Johnson is embracing the health care policies of socialist Bernie Sanders or those of the incredibly unpopular Hillary Clinton. Does Lon Johnson agree with socialist Bernie Sanders that Obamacare needs to be expanded or does he agree with Hillary Clinton that Obamacare is working perfectly?” –NRCC Spokesman Chris Pack
