It is really simply to understand the Democrats passed Obamacare along strictly partisan lines. The Republicans are going to pass another plan along strict Republican lines. Both plans have will have major flaws and neither plan will work. However by passing a strict Republican plan maybe, just maybe the Democrats will sit down and work with the Republicans on a bipartisan plan something they will never do as long as Obamacare exist. A bipartisan plan that will ultimately repeal and replace both Obamacare and Trumpcare or what name you want to put on it. 
The new plan should have tort reform and ability to buy plans across state line along with other ideas.
