Money has got to be a factor in these races. And with the RNC in turmoil, I think Democrats will continue to outraise their opponents.
" In at least six of the most competitive Senate races, Democrats out-raised their GOP opponents.
Five Democratic incumbents raised more money than their GOP opponents. Four of those incumbents more than doubled their challenger's fundraising haul.
One of the most vulnerable Republican incumbents, Sen. Ted Cruz (R-Texas), was out-raised by his Democratic challenger Colin Allred."
And there you are again, Texas.
