In 2017   Canadian Prime Minister Trudeau  learned a lesson about the power of social media.
 Trudeau 's January tweet "isn't necessarily the sentiment being held by a lot of Canadians".
 Mr Trudeau  ended 2017 in an ethics quagmire partly of  his  own making.
Meanwhile   Trudeau 's finance minister  Bill Morneau  is struggling with his own ethics troubles.
A mid-December poll by the Angus Reid Institute indicated that for the first time since his election   Trudeau 's approval ratings had dropped below 50%.
 Trudeau 's ratings are still strong for a politician  but Kurl says there is "perhaps a little bit less adoration and a little bit more exasperation with the prime minister".
As the two rival leaders find their feet - and if  Trudeau  and  his  ministers keep handing them easy ammunition - 2018 could also prove a rough ride.

Undersheriff Kevin McMahill of the Las Vegas Metropolitan Police Department  said at a press briefing the department has been exploring every aspect of Paddock's life  from birth to death  in search of an explanation.  He  said they have looked into details regarding Paddock's personal life  political affiliations  social behaviors  and economic situation â but answers remain evasive.
"We have been down each and every single one of these paths trying to determine why. Trying to determine who else may have known of these plans  " McMahill  said  adding that the rumors and speculation that have abounded in the wake of the shooting have been unhelpful to their investigation.
"In the past  terror attacks or mass-murder incidents  motive was made very clear  very clear in most of those cases by a note that was left  by a social media post  by a telephone call that was made  by investigators mining computer data  " McMahill  said. "Today in our investigation  we don't have any of that uncovered. I wish we did. We will and are continuing to investigate with great tenacity and hope to arrive at an answer."
 McMahill  also shot down several prevalent rumors that have circulated throughout media reports  telling reporters that they are confident no second shooter was in the room with Paddock during the attack.  He  said  he  could not  however  confirm whether any other people knew about Paddock's plans to carry out the shooting.
 McMahill  also said investigators do not believe anyone other than Paddock accessed  his  suite before the attack  despite reports suggesting a room key was used to enter  his  suite while Paddock's car was outside the hotel's parking garage.
 He  also said the Tannerite â an explosive powder used for long-range target practice â that was recovered from Paddock's home was not in a condition to be used in an IED  as others had questioned.  McMahill  said  it  was also unclear what Paddock intended to do with the tannerite.
Investigators are  however  "keenly interested" in Paddock's medical status at the time of the shooting   McMahill  said. The Las Vegas Review-Journal recently reported that Paddock had been prescribed the anti-anxiety drug diazepam â also known by its brand name  Valium.
"It's really imperative that the listening public have a very clear understanding that there are still a number of people out there that know that something looked out of place  " McMahill  said. "Someone may have been acting suspiciously that night  or in the years prior  the months prior. Somebody that may have seen something or know something."

General McMaster forgot to say that the results of the 2016 election were not impacted or changed by the Russians and that the only Collusion was between Russia and Crooked H  the DNC and the Dems. Remember the Dirty Dossier  Uranium  Speeches  Emails and the Podesta Company! â  Donald J. Trump (@realDonaldTrump)  February 18  2018
Trumpâs fixation on the legitimacy-sapping accusation that the Russians âimpacted or changedâ vote tallies to put  him  in the White House feeds this conspiracy theory of mine. What set off alarms for me was the last sentence in the Timesâs paragraph about Trumpâs McMaster tweet.

Tribe also took on the Russian-impact issue and came to virtually the same conclusion as Price. âAlthough itâs no doubt impossible in a scientific sense to determine what the outcome wouldâve been without Putinâs meddling â Tribe said  âsurely we know â to the degree things like [this] are ever knowable â that the perfect storm that put  Trump  over 270 electoral votes  with the help of under [80 000] votes in MI  PA  and WI  wouldnât have occurred had any one of a multitude of factors been changed even a little.â Among those factors  the Comey letter  Hillary Clintonâs campaign in those three states and âRussiaâs efforts to undermine Hillary in several ways  including by hacking  suppressing the minority vote  encouraging voters to go for Bernie [Sanders] and Jill [Stein]  getting unwitting Americans to put on skits of Hillary in prison garb and behind bars  spreading BS about voter fraud and ID theft  and lots of other crap.â
