Immediately he acts like he has huge momentum and the Republicans start tearing down America's social fabric as if they have any kind of mandate.
To be fair, anyone would have acted the same if they had control of all three branches of government, no matter how fake their mandate it. They have the legal power, and that is mandate enough. Even if Romney, Jeb, Kaisich, or Powell had won, they'd set about dismantling ACA with Ryan and McConnell cheering right behind them.
If anything, it's kind of related to how Obama and the Democrats came into power in 2008 because they had a mandate to fix the economy. They went further and tried to restructure the healthcare system, however their first step was the individual mandate to buy healthcare on the threat of tax penalties with exemptions for low income. This gives us a lot of good things like requiring insurers to insure those with pre-existing conditions, somewhat halting the rise of health costs (which are still rising faster than inflation), getting healthcare technology up to date, etc.. However, the people footing the bill didn't give them the mandate to do this. Now, this could have been passable had healthcare been really cheap, say public option or single payer (not slow health costs, mind you, people want to see it DROP before they think about footing the bill). But that wasn't the case, and the health costs pissed off enough people that the Democrats have been hemorrhaging political power for six years. Repealing ACA, as much as you could point to new enrollment numbers or how red states benefit from ACA, is area that put a large chunk of voters in the GOP camp.
So the same could or couldn't happen to the Republicans if they overstep their "mandate" guidelines.
Now we find out that Comey basically did, indeed, throw the election to Trump,
Well, they're looking into that right now, for intent anyway. It probably happened, but there's a chance he just unintentionally fucked up. He's not alone though. Chaffetz who keeps getting voted back in by his constituents has been at this for a long time, as have other GOPers.
So it's bad, but
