Don’t be fooled by Trump’s and Republican promises to “repeal and replace” Obamacare. They could repeal it, but they can’t and won’t replace it.
They’ve tried for years to come up with a replacement that keeps at least as many people covered. Their “replacement” never appears.
So why do Republicans want to repeal Obamacare and leave millions without insurance? Because it would mean a huge tax windfall for the wealthy.
