Both party politicians did. I was once a democrat, then a republican, then finally changed to independent. This will provide me with the freedom to pick the candidate that mostly reflects my ideals. It doesn't matter to me, which party that person belongs to. I'm not sure why more people hadn't done what I did, because the party-politics shifts with the candidate in power. Look what happened when Donald Trump became president. He instituted the tax reform that gave most of the benefits to corporations and the wealthy, and our national debt grew. https://www.politico.com/news/2020/01/28/federal-deficit-one-trillion-trump-107901
Many old guard republicans left the party. FACT: Democratic administrations are better at making Americans become richer. Republicans are supposed to be the party of fiscal conservatism, but you wouldn't know that by their spending. https://www.politifact.com/factchecks/2019/jul/29/tweets/republican-presidents-democrats-contribute-deficit/
And, President Trump's Economic Scorecard FORBES: NICK DESANTIS
The U.S. Treasury Department publishes a 36 page monthly statement that has all sorts of information about where the Federal government receives its “income” and how it is spent. In the most recent report ending in September 2018 for the full fiscal year 2018 it shows that the federal budget deficit increased from $666 billion in fiscal 2017 to $779 billion in fiscal 2018, an increase of $113 billion or 17%. In the same report corporate tax receipts dropped from $297 billion in fiscal 2017 to $205 billion in fiscal 2018, a decrease of $92 billion or 31%. The $92 billion would account for 82% of the increase in the deficit.
I don't think Donald Trump was ever a good manager of anything. He's now bankrupting our country. He has practice; as a civilian he declared bankruptcy at least four times. Most businessmen who declare bankruptcy once do not get a second chance, but Trump's rich daddy rescued him. The only rescuer for our national debt are tax payers like you and me. Political scientists declared Donald Trump, "worst president in history." It's more than just about his poor management of our finances. Our allies trust Putin more than Trump.
