There is nothing illegal about a public official not releasing his tax returns for public consumption, whether others have done so in the past, or not, and Democrats are absolutely writing new laws over this, and digging up a bad law from the 20s targeted at bootleggers. Several prominent Democratic members of Congress have also not released tax returns. Where are their fellow Democrats demanding they release them? You won’t hear it because they are just trying to embarrass Trump, not enforce any kind of rule of law. Furthermore, Democrats in Congress have never been so brazen in calling for the destruction of constitutional norms. They, and especially the presidential hopefuls, have called for the eradication of the electoral college, the abolition of the Senate, packing the Supreme Court, and striking down the second ammendment. Several Democrats in Congress have openly called religious liberty into question, suggesting that holding certain religious views disqualifies people from holding public office. Democrats at the state level have sued over every constitutional executive policy change Trump has enacted and gotten Democratic appointee judges to issue injunctions to stop all of them, clogging up the Supreme Court before these petty decisions get struck down.
Trump was wrong to use presidential emergency powers to circumvent Congress to address the border wall, but Obama largely set the precedent before him in using executive powers to circumvent the legislative branch when they wouldn’t pass the laws he wanted. And it is many of these very executive overreaches that Trump has tried to reverse that Democrats have opposed in the courts. Right now presidential candidate and senator Kamala Harris has declared that as president, if Congress doesn’t pass the gun control legislation she wants, she will enact it through executive fiat. Democrats have no interest in upholding constitutional norms. They only have an interest in furthering their agenda. I oppose Trump overreaching his constitutional authority, and I oppose any Democrat overreaching their Constitutional authority. And these attempts by Democrats to try to force Trump to release his tax returns are nothing more than a temper tantrum and they are increasingly disrupting the rule of law to get their way.
