1.2 percentage points which is the difference between 5 percentage points and 3.8 percentage points in a close race is indeed a big difference and a big exaggeration on your part.  Right - and the article said that even the Republican distanced herself from Trump.  Democrats are closing the gap in all of the recent races in Republican strongholds, not because we had good, compelling candidates but because Republicans are losing their advantage, even with the gerrymandered districts.  Hopefully the Supreme Court will do the right thing.
