It seems that the most recent voter weights are from 2014. Just confirming that the 2016 ones are not available yet.
I am just confirming that for IPUMS-CPS the voter supplement weights are not available (yet) for the 2016 election
Actually, the voter supplement weights are available, we just neglected to add them to the official VOSUPPWT variable. As noted in the voter supplement sample notes these sample weights are identical to the basic monthly sample weights (WTFINL). We will get this updated with the next data release (likely in a few weeks). In the meantime you can use the WTFINL weights in your analysis.
