Steve Curtis  the former chairman of the Colorado GOP  has been found guilty of voter fraud for forging his ex-wife’s signature on a ballot.
As The Denver Post reports   Curtis  may face up to three years in prison for forging  his  ex-wife’s signature on a Colorado ballot in November 2016 after she’d moved to South Carolina in 2015.  He  was arrested in February after handwriting analysis and DNA testing revealed  he ’d committed the forgery.
 Curtis  pleaded not guilty to the charge and claimed that  he ’d signed  his  ex-wife Kelly’s ballot during a middle-of-the-night diabetic episode and accidentally mailed it the next day.
As Salon noted earlier this year   Curtis  blamed Democrats for forging votes and committing voter fraud on his radio show last year.

"We would oppose any violence if that were to take place "  State Department spokeswoman Heather Nauert  said in response to reports that this kind of coordination was being considered. "We hope our voices will be heard in a very strong fashion that we oppose violence on any side of this."
 She  was responding to a report that Iran and Iraq plan to seize control of the border crossings around a semi-autonomous region of northern Iraq that is populated by a Kurdish ethnic minority that plays a crucial role in the U.S.-led coalition to defeat the Islamic State. The tensions have arisen because the Kurds voted in support of breaking away from the rest of Iraq to form their own state  despite opposition from Baghdad and the United States.
 Nauert  took a cautious approach to the diplomatic crisis. "The United States does not want to do anything that would inflame tensions  that's why I'm going to be very cautious with my words "  she  said during Thursday's briefing. "We will continue to offer our assistance to facilitate any dialogue if we are asked."
 Nauert  said  she  had not heard of a request for the United States to close its consulate in northern Iraq.
"Our relationship with the Kurds  in our view  will not change "  she  said.

Jon Gruden  has a career record of 95-81 (.540) with nine playoff appearances and one Super Bowl victory in 11 seasons as a coach. (Kirby Lee/USA TODAY Sports)
 Jon Gruden  was welcomed back for a second stint as Oakland Raiders coach on Tuesday  now  he âll be tasked with getting them back to the postseason. Based on  his  starting point  however  an immediate return to the playoffs is unlikely in 2018.
[Brewer:  Jon Gruden  is âa big effinâ dealâ to the Raiders  but perhaps even bigger for all coaches]
So where can  Gruden  make up ground and quickly improve this roster? The wide receivers â once thought to be a strength of this team â may need a makeover.
Amari Cooper produced even fewer yards per route run than Crabtree (1.5)  and was ranked 60th out of 78 qualified receivers for his on-field performance. Both need to be better in 2018. If not   Gruden  is going to have to find Carr a top target to throw to.
 Gruden  has even more work cut out for  him  on the defensive side of the ball. Oakland allowed 2.1 points per drive last season  the fourth-most in the league  with a 101.8 passer rating against  the third-worst in football in 2017. To put that in perspective  opposing quarterbacks performed as well as Carson Wentz â an MVP candidate before  his  season-ending injury in Week 14 â against the Raiders while the league average was closer to that of Andy Dalton (86.6).
