This is a testable claim. So let's test it.

The first thing you would expect to see from a Part-Time America is that the number of part-time jobs added would rival the number of full-time jobs added. But in the last year, new full-time jobs outnumbered part-time jobs by 1.8 million to 8,000. For every new part-time job, we're creating 225 full-time positions.

Okay, but one year is just one year! Let's keep looking.

The second thing we should expect to see from Part-Time America is a growing number of part-time jobs since Obama came into office and started passing laws. Here's a graph showing the number of people working part-time for economic reasons since March 2010, the month Obamacare was passed.

Huh, nothing there. In fact, the number part-time workers has fallen in the last four years.

Okay, well, raw numbers can be deceiving. After all, the labor force has declined since 2010. So let's graph these part-time workers as a share of the labor force. Surely that will show a rising line...
