The tax returns are a red herring.Even if he releases them it won’t make any difference.
You are probably correct. Trump has been preparing to run for President for years now, and certainly would have his tax returns in "order" And it certainly won't matter to his supporters what is in them. he could have claimed Hillary as a dependent, and it won't alter his supporters thoughts.
BUT - it WILL alter and cast doubt to the independents, and crossover Dems that Trump has to attract to win.
Everyone here on this site honestly knows deep down that not releasing his taxes will be pounded over and over and over by the MSM , and that will steel his supporter's zeal, but cast doubt in every other cross over voter Trump has to attract to win.
And isn't that the whole point of Trump's appeal?? That he can win?? It is simple - he has to release them. Sorry - but it is a fact.
