I worked in the campaign field in PA. when Santorum was running, their machines are not connected to each other, nor are they connected to the internet and they have quite a system to prevent voter fraud...I seen it work, and it’s really a clean, legal procedure...Hillary doesn’t have a chance...Ed Rendell even said there wasn’t any way that Trump didn’t win fair and square and Rendell is the voice of the Dems in PA...or was...
I think there are three kinds of vote fraud - the most common of which is not even called fraud - namely, letting illegals vote.
This is the most common because there is no risk - in fact it is legally protected where voter ID is not required or where you have a POTUS who publicly encourages it. There must be tens of millions of illegal votes - 90% plus for the democrat.
Next, you have poll workers cheating by just going down lists of registered voters who didn’t vote and just pushing the button over and over. This is very localized and happens only in certain inner city precincts so extremely democrat that republicans do not dare show up. These crooked precincts are rare but they can generate a lot of fake votes. Black precincts in Philadelphia did this for Obama - it’s not even organized from the top - more like spontaneous opportunistic looting. I don’t think there was much of this for Hillary.
The third kind is what everyone talks about - some sophisticated hacker rigs a machine or replaces the chip or whatever. Very doable if one has the right skills, but also extremely risky - if you are caught doing this you could go away for a long time. So I doubt this happens much.
I think the bulk of vote cheating is accomplished by not requiring voters to prove they are citizens or that they have not already voted. Bussing people and paying people to vote for a certain candidate - these things are not even illegal - if you get caught nothing happens.
The more liberals become congressmen and judges the more illegals and criminals and cheaters will vote, because they want it to happen - they loosen the laws and make enforcement impossible - illegals and criminals and cheaters vote exclusively democrat. Honest citizens vote honestly republican and democrat.
Trump should force a recount in sanctuary cities for the purpose of identifying illegals casting a vote. These votes should be subtracted from the 2016 totals.
Casting a vote as an illegal should be grounds for immediate deportation.
