Today's installment of campaign-related news items from across the country.* Despite Donald Trump's focus on illegal immigration, his third and current wife, Melania Trump, reportedly worked in the United States without the proper permits.* According to a Wall Street Journal report, the National Enquirer tabloid, a prominent Trump backer, "agreed to pay $150,000 to a former Playboy centerfold model for her story of an affair a decade ago with the Republican presidential nominee, but then didn't publish it."* Why is the presidential race so close? In part because of Trump's strong support from white voters without college degrees and low-information voters in general.* NBC News reports that "a number of Trump loyalists" are positioned for powerful roles in a Trump administration should the GOP ticket win tomorrow. Among the possibilities: Rudy Giuliani for attorney general, Newt Gingrich for secretary of state, and retired Lt. Gen Michael Flynn for defense secretary or national security adviser.* Over the weekend, Trump focused much of his message on his anti-refugee stance.* At a Trump event yesterday, Rick Santorum reportedly told a Republican audience that President Obama and Hillary Clinton are "certifiable traitors to our country."* When former Sen. Gordon Humphrey (R-N.H.) was in Congress, he was regularly a thorn in Democrats' side. Yesterday, however, the New Hampshire Republican announced his support for Clinton's candidacy and appeared in a new video released by the Democratic campaign.* Former half-term Alaska Gov. Sarah Palin (R) is apparently campaigning for Trump in Michigan. Aware of her candidate's deficit in polls, Palin told Fox News last night, "[P]olls are only good for strippers and cross-country skiers."* On a related note, former New Hampshire Gov. John Sununu (R) told supporters at a Trump rally on Friday afternoon, "Do you think that Bill was referring to Hillary when he said: 'I did not have sex with that woman?'"* A senior Trump campaign official, Brad Parscale, told Bloomberg Politics he expects a "close" race. "It's like predicting your wife's mood. You have no idea what you're going to get until you get home," Parscale said, apparently hoping to make the gender gap even worse for his party.
