I think he intends to work on the influence biased and/or paid MSM media has on the elections. I have no doubt that he will have the entire voting system investigated. And I think he intends to improve, modernize and safeguard the election machines and systems. Trump doesn't do things half way.
I had posted a Drudge poll result on my FB page that showed Trump had the lead 70/30. Those types of more conservative sourced polls were never discussed on MSM. One of my leftie friends even accused me of posting a poll result from a conservative site, as tho that was a crime.
This paid MSM (Presumably paid by the Democrats), didn't do their jobs properly in destroying Trump, because they spent an incredible amount of time hanging onto and publishing his every self aggrandising word, to the almost disregard to the other candidates.
As for polls, they mean nothing except the final one. But Trump said he wouldn't have accepted the result unless he won; which he did. But for him to imply that a vote against him was a rigged vote was invalid, shows what a complete narcissist he his. He's surrounding himself with the the very people he denegrated, and parading him and his family like the Kardashians, with a similar vacuous outlook.
