|"the Pentagon just handed Trump a billion to build the wall"|
Which is money that we won't be able to use for our military, but will instead use to build an ineffective wall...
"and Obummycare may be ruled unconstitutional!"
And replaced with what? If this happens there are an estimated 21 million people who will lose their health care. The overwhelming majority of those are in states that voted for Trump in 2016 - how do you think that will go over with the voters in those states in 2020?
"Repeal and replace" suggests that you have an alternative - but the GOP has nothing to offer, and has had nothing to offer over all the years they've tried to repeal the ACA. Instead of "repeal and replace", their attitude seems to be "repeal now and we'll figure out something later... maybe."
It's comical that many of the GOP faithful hate the idea of "Obamacare" but love the Patient Affordable Care Act because it gave them access to health care they didn't have before - and don't realize that the two things are the same.
