Based on his statements and actions, a Trump presidency with a Republican-controlled Congress may seem to be the worst election outcome possible for disabled Americans. In a poll cited by CNN, for example, people agree that mocking a reporter with the joint condition arthrogryposi was the most egregious error that Trump made during his campaign.
However, those worries may not entirely be warranted. Trump is a businessman and a television personality. He says what will get him a deal, acts in a way to give him an audience and, in the case of the election, promises what will get him votes. For example, one of the hallmarks of Trump’s campaign was his promise to repeal and replace the Affordable Care Act. Since winning the election, though, “Trump [has] said he would [at least] like to keep the portions of the law requiring coverage of pre-existing conditions and children living at home under the age of 26.” From what I can determine, Trump simply wants his name tied to a major legislation. (He wants to keep some of the principles of Obamacare, but replace the wording with some synonyms, so that people will call it Trumpcare?)
As for the Republican-controlled Congress, it is good to remember that most people, including Senators and Representatives, are related to or have some association with a disabled person. During the Obama Administration, almost half of the brain injury-related legislation that became law were sponsored by Republicans, specifically 8 of 20. As I noted in the past, Republicans do care. While Hillary Clinton may have won the popular vote, it is best not to presume that a Trump presidency will negatively impact those with a brain injury or all of those with a disability.
