As opposed to Trump the difference is humungous. A Clinton win assures a change in the balance of SCOTUS and that's a big deal. The GoP won't have control of all three branches of the federal government and that's huge. But legislatively gridlock will remain, strong as ever. No way the GoP will allow HRC any wins that negatively effect them in 2018. Change in the tax code? Doubtage. An infrastructure bill to repair or replace & add jobs, spuring economic growth? Nah. Immigration? No chance. The ownerous student loan, college costs problem? Ain't gonna happen if it costs $. There might be a sliver of hope to address the ACA issues. And of course the oval office will be occupied by a bright,sane, level headed woman (the woman part is a monumental change) compared to Trump. In sum, in spite of all the political bs proposed dreams of HRC, I doubt we'll see any difference from status quo legislatively. There's hope a new SCOTUS could overturn "citizens united" and end infringement of voting rights law.
