Pete Hoekstra, controversial US ambassador to Canada, has also accused Canadian officials of interfering in US elections

The US ambassador has suggested Canada could be blamed if Republicans perform poorly in next week’s midterm elections, the latest intervention from a controversial figure who has been accused of inflaming a bitter dispute that has angered and baffled residents of both countries.

On Wednesday, CTV news reported that Pete Hoekstra told business leaders at a closed door meeting that if a number of swing races – including Maine and Michigan – go to the Democrats, it could make things harder for Canada because Donald Trump might try to blame the loss on it.

Republicans have condemned the presence of two Dan Sullivans on the ballot, calling it a ploy to split votes

Alaska Democrat Mary Peltola’s campaign was behind an effort to recruit a challenger with almost the same name as the Republican US senator Dan Sullivan, both of whom will appear on the ballot in next week’s midterm elections, the New York Times reported on Wednesday.

Republicans have condemned the presence in the race of two candidates named Dan Sullivan – one the two-term US senator, the second a retiree living in south-eastern Alaska with scant political experience – calling the newcomer a ploy by Democrats to cost the incumbent re-election by splitting his supporters.

James O’Keefe and Cam Higby were trying to show vulnerabilities in allowing a voter to vouch for another

Two rightwing influencers have been charged with felonies in Minneapolis over attempts in the state’s election primary to disguise themselves in what they called “Muslim garb” and claim they were local voters.

James O’Keefe and Cam Higby went to polling places in Minnesota during the state’s August primary in an attempt to show vulnerabilities in the practice of “vouching”, where a registered voter from the same precinct can vouch for another voter’s eligibility.

Both Obama and Trump are on the campaign trail, but only one of them appears to be descending into madness

Barack Obama versus Donald Trump. It is the presidential election that never happened but has come to define an era of US politics.

Obama is back on the campaign trail for the midterms, still electrifying crowds, earning shouts of “We love you!” and skewering his successor. “What’s up with the gold?” he asked a crowd in Detroit. “I mean, he’s got the White House looking like Saddam Hussein opened a Cheesecake Factory.” This has, predictably, set off a mini culture war involving questions of elitism and the tastefulness of chain restaurants.

Circumstances are ripe for change in this onetime Republican stronghold given the current dissatisfaction with Trump agenda, experts say

Donald Trump has repeatedly asked voters to pretend that he is on the ballot in November’s crucial midterm elections. And in the comfortable confines of Arizona’s most affluent and fiercely contested congressional district, Trump is definitely on voters’ minds.

But whether that helps or hurts the warring congressional candidates in this sun-drenched swath of suburbia, where Teslas and walled-in luxury homes dominate, depends on who you ask.

US health secretary falsely claims at Mike Rogers rally that Arabs have never won major prizes in science or literature

Robert F Kennedy Jr, the US health secretary, faced backlash on Wednesday for a “wildly racist tirade” during a campaign stop in Michigan in which he falsely asserted that Arabs never won leading awards in science or literature.

Kennedy was speaking at the Monday night event in Grand Rapids in support of Mike Rogers, the Republican US Senate candidate trailing his Democratic midterms opponent Abdul El-Sayed, who is Muslim, in polling.

For months, Mary Peltola’s campaign for Alaska’s Senate seat has denied any connection to a separate campaign launched by a man who, coincidentally, shares the exact same name as Peltola’s Republican opponent, Dan Sullivan.

New reporting from the New York Times undercuts that claim. The outlet reported, based on interviews, obtained text messages and legal filings, that the Peltola campaign had not only recruited Mr Sullivan (not the Republican), but had sought out a number of Dan Sullivans across the state for potential candidacy, as well as others who could peel votes away from Peltola’s main opponent.

President at Texas campaign rally hails deal struck with post-Maduro government as ‘greatest oil victory in history’

Donald Trump suggested Venezuela would become the 51st state of the United States on Tuesday as the president showed off a tanker he claimed had “one million barrels of oil on it” from the country, nine months after deposing its president.

At a campaign rally in Corpus Christ, Texas, Trump touted a US oil deal with Venezuela, which the US attacked in January, capturing its long-serving leader Nicolás Maduro.
