The GOP looks like it can
maintain its majority in the Senate, but the main Senate super PAC has decided to spend $21 million more in six races just to be on the safe side. The Senate Leadership Fund
has moved its concentration to New Hampshire, North Carolina, Indiana, Missouri, Nevada, and Pennsylvania.
Republicans have become more confident since they have seen
voters separate GOP presidential candidate Donald Trump from the Senate candidates. This week,
The New York Times Upshot blog said the GOP had a 53% of maintaining the majority. That same blog gave the GOP only a 40% chance in August.
