  We use 5,337 spectroscopic $v \sin i$ measurements of Kepler dwarfs and
subgiants from the APOGEE survey to study stellar rotation trends. We find a
detection threshold of 10 km/s, which allows us to explore the spindown of
intermediate-mass stars leaving the main sequence, merger products, young
stars, and tidally-synchronized binaries. We see a clear distinction between
blue stragglers and the field turnoff in $\alpha$-rich stars, with a sharp
rapid rotation cutoff for blue stragglers consistent with the Kraft break. We
also find rapid rotation and RV variability in a sample of red straggler stars,
considerably cooler than the giant branch, lending credence to the hypothesis
that these are active, tidally-synchronized binaries. We see clear evidence for
a transition between rapid and slow rotation on the subgiant branch in the
domain predicted by modern angular momentum evolution models. We find
substantial agreement between the spectroscopic and photometric properties of
KIC targets added by Huber et al (2014) based on 2MASS photometry. For the
unevolved lower main sequence, we see the same concentration toward rapid
rotation in photometric binaries as that observed in rotation period data, but
at an enhanced rate. We attribute this difference to unresolved near-equal
luminosity spectroscopic binaries with velocity displacements on the order of
the APOGEE resolution. Among cool unevolved stars we find an excess rapid
rotator fraction of 4% caused by pipeline issues with photometric binaries.
