Declare the complex survey design like: 

proc surveyfreq;
  stratum STRATUM;
  cluster CLUSTER;
  weight WEIGHT;
  table VOTE PARTY VOTE*PARTY ;
run;

Or: 

svyset CLUSTER [pweight=WGT], strata(STRATUM) vce(linearize) singleunit(centered)

Until the 2006 pilot, clusters and strata were published as a single variable. This could be broken apart like: 

compute STRATUM = trunc(v040103/10).
compute CLUSTER = v040103 ‐ (10*STRATUM)
