The reason the Republicans are lying about having a Republican alternative to Obamacare is that Obamacare IS the Republican health care plan that was advanced by Richard Nixon, and on and off by Republicans thereafter until Romney tweaked it and enacted it in Massachusetts. Today's Republican liars are claiming that they will repeal Obamacare and replace it with better, cheaper insurance, and do it in such a way that there is no gap in coverage for anyone (Trump) and in such a way that no-one -- not one person -- will be less well off after the repeal/replace than they were before (Ryan).  I think they're lying through their teeth, just as they have been from the inception of the ACA. However, as Elizabeth said above, "If the ACA is scrapped and replaced by something better we will applaud." I think they can't do it; won't do it; and don't intend to do it; but if they do, who would not be thrilled?
