Another of his main supporter groups are college students, who have been being purged from voter rolls for years due to frequent mailing address changes (this happened to me in Pennsylvania in 2008). There are more logical explanations for this than can be mentioned here, Occam&#x27;s Razor.<p>Same for exit polls.
