I dont think you should vote for Trump, but here are two major reasons to vote for a Republican senate:
1. To Stop the Democrats from packing the court and destroying a core part of our republic forever
2. So we can keep the 2017 Tax Reform which really did help the economy(there is a reason the economy is an issue Trump still gets high marks on and that is thanks to the 2017 tax reform Bill).
You keep saying that the 2017 Tax Reform was good. However, let me ask you a question: As of 2016, the US debt/GDP ratio was 105%.
Also, the economy, while not doing super amazing, was doing "fine" under the late Obama administration, with a 2% annual GDP growth on average. Growth was slightly stronger in 2018 and 2019 but even then it was at 2.5% on average between the 2, so the increase was minimal.
As for the other big indicator of unemployment, the US unemployment rate was just barely below 5% in 2016. That is a pretty good number and in fact is the barrier where society is considered to have "full employment". Even if you argue (reasonably) that Trump's tax cut did marginally decrease unemployment, is it really a good thing if it sent the debt up for a marginal improvement in unemployment?
TL;DR: Why was a tax cut that at best had a marginal effect in stimulating the economy, and instead would increase the debt any good? Shoudn't Trump literally just have kept the economy as it was and gradually reduce the debt instead of passing tax cuts for no reason?
