PHILADELPHIA (CBS) — Former Pennsylvania State Senator Bruce Marks asserted that there could be massive voter fraud on election day in Philadelphia and cited his own experience as an example of how it will be carried out.

Marks, during a conversation with Chris Stigall on Talk Radio 1210 WPHT, said the Democrats in the city orchestrated an effort to steal a contest from him over two decades ago.

“We have a sordid history of corruption among the Democratic elected officials and in elections in Philadelphia and my 1993 election to the State Senate is the poster child for that. I give the give the Democrats credit in Philadelphia. They don’t commit fraud every year. They only commit fraud when they have to. They had to commit fraud in order to deny me an election to the State Senate in 1993. They did it through massive absentee ballot fraud. They did it by putting thugs at the polls to keep us from contesting the absentee ballots. They did it through the participation of the City Commissioners, who were directly involved in the wrong doing, ignored our challenges and illegally certified my opponent.”

He explained that it took a federal court ruling to overturn the fraudulent outcome.

“The only reason that I was able to win the election, not in the state court because we all know they’re elected and the Philadelphia machine hand picks the judges there, but we were able to go to federal court and the late Judge Newcomer found that there had been massive fraud that the City Commissioners had participated in, removed my opponent and put me in office. That happened in 1993. It’s documented with a federal court decision. Many of the same people who were in office then are still around now and the fraud continues.”

Marks stated he would not be surprised to seem similar attempts carried out against Republicans this year.

“It’s very important that [Donald] Trump and Pat Toomey, who is, no doubt, going to be in a very close race, they have to have a team of people in Philadelphia observing all of the polling places. And the second thing is, what you do about this in Philadelphia is problematic, but you have to elect good officials.”
