I remember just a few weeks before the 2016 election that the liberals were having orgasms speculating on Hillary's historic landslide victory. They were speculating that Hillary might even turn Georgia, South Carolina, Kansas, and Texas. We shouldn't be overconfident but we shouldn't be unnerved by such silly speculation, either.
Most people don't pay a lot of attention to mid-term elections until after Labor Day. A lot will change in the next 2 1/2 months, probably a lot of it in our favor.
