It's not a stretch.

Look at the main contention within the party right now -- every candidate except one is pushing to prop up a for-profit healthcare system. The idea of the ACA was okay, but ultimately it left in place the systems which were the real problem, and unsurprisingly it's gotten worse since then.

> Obama was kind of underwhelming

That's a stretch! His healthcare plan was underwhelming, and while that was being dragged through the republicans, he was deporting immigrants at a rate we've not seen since and ordering hundreds of drone strikes. He was not progressive.

Now we're trying to make sure the same type of candidate doesn't fool everyone again. Most of the "dramatic" restructurings we're pushing for aren't "radical" anywhere outside the US.
