The ACA has stood up to all scrutiny. Mitt ran on its repeal and lost. The Supreme Court ruled in its favor and hundreds of votes held to repeal it have gone no where.
The American people despite having an unfavorable view of the law have objected to the methods made by one party to kill it according to polls. And public blame for this shut down falling on the heads of the GOP as the previous one during Clinton. The irony this shutdown will be with little punity as the GOP's gerrymandering across the country has them hold the House regardless. Even with a million more votes on the Democrat side the housed remained theirs because of these district lines.
The blame falls squarely on the GOP. Extortion is no way to govern; they were warned prior that their attempts to circumvent the law would go nowhere in the Senate and if it did by some miracle make it past there the President wouldn't have allowed his signature legislation to go anywhere and would have vetoed it.
And a special FU to Ted Cruz for squandering the time to debate the issue, leading his party into this hole with no plan as he stuffs his coffers with the donations from dimwit followers.
I like the Lincoln mention here as a better President than Barack with better policies. Lincoln's policy divided the country in two and landed it in a bloody civil war.
