Because Cruz's position all along is repeal Obamacare, period. Not repeal and replace. Because he, like most people, understand that there is nothing the government can do that won't be either horrifically expensive or will do nothing. Currently Trump's written plan will do nothing. In campaign rallies he's also expressed interest in the horrifically expensive solution as well. So who knows?
His website contains a whole lot of boob bait, an obnoxious amount of self-congratulation and a glaring dearth of actual solutions. Kind of like Cruz himself.
It would be more accurate to apply your description to the Trump website.
Hello? Cruz does not give a copulating rats behind about Kennedy care... Cruz has deceived himself that he is http://talkingpointsmemo.com/livewire/heidi-cruz-face-of-god and has attempted to sow that deception across this nation.
Cruz has lost. At this point he’s doing the bidding of his GOPe masters by staying in the race to split the party and give the win to Hillary.
No real conservative would do that, just as no real conservative would support a candidate who would.
