While that was my initial reaction one thing to remember is that this survery was of likely Rep primary voteres which means they have a much higher likelyhood of knowing the Lorge family name. WHile Lorge has not done a lot, Michels was tottaly unknown before he entered the race.
The thing is how is the survey suspect? The guy who did it is Bush top poller--would he jeopordize his reputation on a primary race? In addition, if we say his survey is suspect that gives the Dems fodder to use against Bush.
