We report the first measurements of inclusive W and Z cross
sections times leptonic branching ratios for p anti-p collisions at s**(1/2) =
1.96 TeV, based on their decays to electrons and muons. The data correspond
to an integrated luminosity of 72 pb-1 recorded with the CDF detector at
the Fermilab Tevatron. We test e-mu universality in W decays, and we
measure the ratio of leptonic W and Z rates from which the leptonic
branching fraction B(W --> l nu) can be extracted as well as an indirect
value for the total width of the W and the CKM matrix element, |V_cs|.
