So you have confidence in the Voting Machines here . Yes. Reporter republican elections commissioner al schmidt disagrees. He wrote a report on voting irregularities during the 2012 election. There have been dozens of cases but only 10 prosecutions. Voter fraud does occur. But that is a completely different animal from vote rigging right or ramp ant voter fraud. Which would involve hundred of president ial election. Schmidt says even without a paper trail, the electronic machines are safe because they do keep a digital record of votes cast. And he points out, the individual machines are not connected to the internet. Our Voting System has more in common with a household appliance than it does with a laptop or anything like that. That means they dont believe the Voting Machines themselves to a cyberattack. Scott, with other aspects of the system.

Digging networks of tunnels t and launching surprise assaults like this one in the town 200 miles west of baghdad. Planting its fighters amongst desperate refugees to wreak more violence is a tactic that isis will find hard to resist.

Two deer can be spotted 150 feet away. But in the worst performing pickup tested, the 2016 chevy colorado, i driver can barely make out the person. You probably shouldnt be driving faster than 35 miles an hour with the low beams on this pickup. You need to see. And still be able to avoid a crash. While all of the headlights meet federal requirements. Such a poor showing in the tests will likely force changes. Ed low from motor trend.
