No, I want to know everything I can about any candidate, but at their option or their opponents research, not a government mandate.
The only thing a tax return can tell us is how much they made, how much they contributed to charity, and how much they wrote off. In other words for the presidency, it tells us nothing. It only tells us of their personal dealings which is really none of the voters business.
Now if they have or had any shady or illegal dealings, do you think they would put those deals on their tax return?
First, California is not forcing Trump to do anything. Trump is choosing to put his name on the primary ballot and thus must meet the same requirement as other candidates both presidential and gubernatorial which is well within the purview of the state.
Second, the republican party in California will send Trump delegates to the convention whether he is on the ballot or not. The presidential primary election in California just shows voter preference. The state committee actually decides who the delegates will be.
Tax forms tell us far more about a candidate than just the money they made and charitable contributions. It tells us how the money was made, the candidate's financial connections domestic and abroad, to who the candidate owes money, investments both domestic and foreign. In short, tax returns reveal where conflicts of interest may lie. Without tax forms, the voter has to rely on the honesty of the candidate and political hacks that create false news as fast as Trump tweets. This is why all modern day presidential candidates except for Trump have released their tax returns.
If your tax preparer is listing who you owe money to, how you are connected to the money, how your money was made, you better first fire them, and secondly, call the authorities.
Your tax form will contain a W2 if you are working for somebody else that has the various taxes and gross income listed. But nowhere does it say who you owe money to perhaps outside of a bank, and the only reason for that is if you are deducting interest rates. It doesn't say how you made that money either. The IRS has no idea I'm a truck driver.
It is a nice list of extremely poor excuses to get Trump's tax returns, when in reality, it has nothing to do with his presidency or anybody running for President. This law is nothing more than blackmail which just about any non-commie court can clearly see.
You cannot make additional requirements to the Constitution as a political attack (which this is) yet alone make additional requirements for any other reason.
Now if this law had a chance at hell in not being defeated by the courts, then Trump or anybody can make up a phony return saying anything he wanted to. There is no way to check that against the IRS files because the IRS files are off limits to everybody.
