If he is confident its because Republicans are already skilled at the theft of elections.
Sorry folks but I was in Vegas on vacation the last week or so and seeing this reply I have to answer it.
JFK stole the election from Richard Nixon and no one said a peep. It is well documented but still no one wants to speak ill of the dead. He was so unpopular that he had to go to Texas, a democrat strong hold at the time, in order to have a chance at re-election. It was common knowledge that President Kennedy used he father’s ties to organized crime to fix the election. Bobby Kennedy then turned around and attacked the people that put him in power setting the stage for the presidential murder in Dallas, dear sweet innocent Bobby had thrown so much political mud that Mr. Nixon was forced to retire from public life until the Kennedy’s were out of power. When Mr. Nixon was elected he did the exact same things that the Kennedy's did but he was vilified for it and no one mentioned that President Kennedy’s Attorney General pulled FBI files and used them to smear political enemies or had an enemies list. Any thefts of elections were learned from the democrat party.
Shall we look at Illinois politics the last half century? A state with the un-official motto of “Vote early, Vote often”. A state where you can count on 150% of registered voters turning out for elections, dead people voting for decades and the like.
How about Miami Florida where democrats are caught with voting machines and blank ballots in their cars and no arrests are made, that was the 2000 election so even with the cheating that was going on the democrats still lost and because they lost scream foul, and that the election was stolen. Or how about when the current laws and rules were not advantageous to the democrats so they hire a bunch of lawyers to try to fix the elections of 2000 and 2004 and when it does not work then they again scream fraud.
Please show me where the Republican Party has shown a half century of fraud in elections, show me republicans that have done the above things. You can’t because it never happened.
