It's almost official. As of this evening, this will be the longest government shutdown in

U.S. history. And Democrats and Republicans are at a standstill, largely over one issue,

health care costs. And it's an issue that's on the minds of millions of Americans this week.

Open enrollment for Obamacare, or the Affordable Care Act, officially kicked off on Saturday.

And when Kevin Foster logged in to check out his plan, he saw a number that made his eyes bulge.

I just thought it was ridiculous. Kevin is 64 years old.

He's a former business consultant and he lives in California.

This year, Kevin paid about $7,000 to cover himself and his wife.

Next year, the total will be more than five times that, $38,000.

I thought there had to have been an error,

and I went through the selection criteria to ensure I was selecting the same plan as I previously had.

And sure enough, it was that amount.

Kevin's plan was the same, but something big changed,

and it's the very thing Republicans and Democrats are fighting over, a government subsidy.

The startling thing is that, you know, you think you plan every year,

and you think you know what your costs are and what you can do and what you spend money on.

And then this one really comes

out of the blue. I can't believe I'm the only one surprised. I think this has got to be shocking

to a lot of people. Right now, the U.S. spends a lot on the Affordable Care Act.

If these subsidies were to continue, the Congressional Budget Office estimates it would add $23 billion to the national deficit next year.

Republicans want to end the subsidies. Democrats want to keep them.

And both sides are still very far apart.
