W+jet cross section measurements at CDF

Using CDF Run II data a set of preliminary differential cross section measurements as a 
function of relevant kinematic variables for $(W\to e\nu) + $ jets production in 
$p\bar{p}$ collision will be presented. The challenges in extracting such measurements 
and the main sources of systematic errors will be investigated in detail.  Finally, an 
extensive comparison between the measurements and the latest LO Monte Carlo predictions 
will be presented.
