EXECUTIVE SUMMARY
GOP candidates pull ahead in vital Senate races days before the November 3 midterms, threatening Democratic chances.
Republican candidates in key races that will determine whether the party retains control of the U.S. Senate have pulled ahead of their Democratic opponents just days before the November 3 midterms.
New polling shows GOP candidates taking narrow leads in Texas, Kansas, Iowa, and at least one recent survey in Ohio and Michigan each.
The latest numbers underscore how small polling shifts could determine control of a chamber Republicans currently hold 53-47.
