The U.S. workforce of 155.4 million has grown by only about 60,000 in the past year, as baby boomer retirements are offset by population growth and modestly rising confidence. The number of people out of the labor force who say they want jobs is 240,000 smaller than this time last year, the Labor Department says. For Republicans, the cavalry ain't coming.

Since sub-6% unemployment before the election is basically baked in the cake, let's talk health care.

The latest numbers show 8 million enrollments in Obamacare health plans (that's the eight), not counting six to seven million new Medicaid recipients. Rand Corp. estimates 9.3 million people are newly insured under the Affordable Care Act -- assuming most who bought coverage on exchanges were already insured. Since 83% of exchange enrollees qualified for premium subsidies, Rand's estimates look conservative.

I'm not a political reporter, and can't expound on cultural issues in Democratic Sen. Mary Landrieu's re-election campaign in Louisiana, Kay Hagan's effort in North Carolina or similar races where Republicans need a nearly clean sweep to pick up six seats to win back the Senate. Neither do I know much about turnout mechanics political reporters believe favor the GOP.

But an economics reporter who knows that Louisiana has 4.5% unemployment, that North Carolina's 6.6% March rate is down from 8.4% last March (state-by-state April numbers aren't out yet) and that in Kentucky, where GOP Senate Minority Leader Mitch McConnell is in a surprisingly tight race, 10% of the state's population bought Obamacare plans or signed up for Medicaid.

And we know that polls, which at RealClearPolitics show a generic House vote of 42% for each party, follow reality with a lag. That's why Yale economist Ray Fair's model -- which uses economic data and forecasts to predict elections -- says Democrats will win 52% of the two-party House vote this year.

If I were a political consultant -- in either party -- I'd memorize the idea that six plus eight holds the key to 2014. One side needs to exploit it. The other side needs to plan defenses against it, lest it be left as helpless as Romney was when September 2012's jobs report hit.

Because, like them or not, six and eight will be this fall's facts on the ground.
