I just got back from Kansas, and did not see a whole bunch of ads. Roberts appears to be running a sad, mealy mouthed campaign.
OTOH, Ed Gillespie of VA just started running attack ads, tying his opponent to Obama; expect him to pick up points on Warner.
Roberts has run a terrible campaign. He believes in the divine right of sons of the Republican National Committee Chairman. A new campaign team has been imposed on him, the are just now starting to hit the airways.
