Which is exactly why the impact of the BOGUS Russia Investigation not only affected the 2018 Midterms but could impact the GOP Senate Majority in 2020.
I don’t expect the GOP to lose the Senate majority in 2020. Depending upon recruitment for House races and $$ support, I’d give them an even shot to win back the House, but like 2018, the Demonrats will cheat like hell (for example, they’ve almost maxed out on stealing every seat in California’s 53-member delegation, with the GOP once holding 26 seats going into 1996, now at 7(!) 22 years hence. The GOP has not defeated a Dem House incumbent in the state since 1994. When you consider how many hundreds of races that have occurred since, it is a numerical/statistical improbability).
