They have had 6 years... how is it that the Republican party was unable to draft a "replace" to the ACA yet?

Because they can't decide who to. The ACA is a well crafted law with only a few parts that might need 'tweaking'. But the Republicans can't get their own people to agree on what parts to replace and to keep.

Think about this. If employees think there should be an alternative to a company's product, but the company is satisfied with the product they have, the only work that can be done is some unofficial musing on what it should be plus, one is NOT going to expend a whole lot of effort into something that they know is not going to go anywhere.

This has been the situation with an alternate to Obamacare.

You can't undo eight years of Obama overnight, unfortunately.

Why did it take the Democrats nearly two years to draft the ACA legislation when they'd been proposing national health care for like 75 years?

It wouldn't get even an audience from the democrat led senate.

I've been saying all along that about 90% of opposition to Obamacare was really just opposition to Obama. For 8 years, whenever Obama agreed with a Republican the Republican immediately changed his mind. Obamacare represented REPUBLICAN ideas! And now Republicans have to pretend the never wanted that.

Their desperation to repeal Obamacare is not about the Republicans having better ideas or wanting something better for American citizens. It's just about wanting to take away Obama's 'signature achievement'.

They seem to want to make a complete plan now out of the few ideas that Obamacare didn't co-opt, like inadequate vouchers, medical savings accounts, deregulation, etc., and the reason Obamacare didn't include those things is that nobody likes them! NOBODY likes them! Paul Ryan's plan to voucherize Medicare went over like a pregnant pole-vaulter. The Republicans can't even pretend these ideas are popular!

This is why they voted over and over to repeal Obamacare when they knew it was impossible, but now that they actual COULD do it, they're paralyzed!

Seth Meyers reported some Republican congressional leader as saying it might take Trump's whole first term to come up with a replacement for Obamacare. Meyers said "What? A whole two months?" 8^)

They have had at least since Clinton's presidency to come up with some type of plan. However they don't want any plan, they would rather not have people of the lower classes get insurance.

There is no plan or any intent. The WHOLE IDEA of repealing the ACA was to give the rich a very...and I mean...VERY... large tax cut.

Obama would veto , read a book

They have no plan
