A little analysis on the claim that Democrats got more Senate votes.
According to
Wikipedia, Republican Senate candidates got 39.3 million votes and Democrats got 45.2 million. However this margin is entirely due to California where the only choices were two Democrats who got a combined
11.9 million votes.
If California had a Republican and Democratic option, and voters voted for those options in the same way as they voted for president, the Democrat would have gotten 8.5 million votes, and the Republican would have gotten 4.3 million. This would mean an overall Senate popular vote of:
All Republicans Senate candidates: 43.6 million
All Democrat Senate candidates: 41.7 million
Warren's claim of a mandate for Democrats also don't hold up when you look at the
popular vote for the House, which Republicans won 49.9% to 47.3%.
