Keeping the major campaign promise is not related to magical powers.
Tell me how he repeals Obamacare without Congress...how does he deal with illegal immigration without Congress? Liberals will just take whatever he does to court otherwise they’ll just pass it when hey inevitably take over next year. Trump would sign the hardest right wing policy but this Congress isn’t going to pass it, period. Trump would sign a clean repeal but Congress won’t pass it.
Trump always talked about having heart, he never advocated throwing all out like some here apparently want to do. Any who paid attention during the campaign know this.
Besides that it might no be possible to keep all promises, most understand that too. A promise is a best case scenario, one that might not happen because there are other factors involved. Remember Trump is working against the uniparty elitist swamp. It is as close to an impossible task as one can imagine. I think Trump’s been doing about as good as anyone could with what he’s got to work with.
