Because you love the Obamacare mandate.
A little honor here? Trump is on record many times as immediately removing Obamacare upon assuming the Presidency. The tired argument of he wants Universal Healthcare is disingenuous because the Universal was clearly defined by Trump as a second system for those unable to afford care any other way ie Medicaid. The vast majority of Americans in Trumps view would have market based insurance and HSAs.
PS Cruz lost about 1/2 of those cases which is average for a lawyer arguing before the Supremes.
