The economy is going great and unemployment is at historic lows among minorities and Hispanics and the Stock Market is reaching new highs under Trump but not everything is positive. Trump, the Republicans, and/or the Democrats have yet to tame the deficit. The United States is still spending far too much and unless someone can get a handle on spending we are not going to be as great again as we used to be.
Democrats don't need to be gleeful though because all you have to do is look at Obama's terms and Spending had a huge increase. The upward trend however really started to explode under Bush 43 but the greatest jump happened under Obama, most likely with the stimulus give-a-ways.
