MSNBC anchor Rachel Maddow on Thursday explained the growing evidence that Tuesday's midterm elections could be even closer than expected.

"If you are sensing a little tension, a little drama, a little frizzante of excitement about the election -- as we're just about five days out from the election ... that is not just you projecting from your own internal levels of anxiety and stress," she noted. "What you are sensing is a true thing that is measurable in the world, never more so than it is pleasurable tonight."

Maddow reported on a new poll showing Democrat Stacey Abrams leading Republican Brian Kemp in the Georgia gubernatorial race by two-fifths of a single percentage point -- 46.9 percent to 46.7 percent.

"That is incredible -- five days out in a statewide race, five days out from the election -- to be separated by zero-point-two percentage points," she noted. "If neither of these candidates gets over 50 percent of the vote, Brian Kemp and Stacey Abrams will have to go to a runoff in December, so if neither one of them hits 50, we will not know who Georgia's governor is going to be until next month."

"But it's not just there," Maddow noted.

She also reported on a new CNN poll showing the Florida U.S. Senate race between Sen. Bill Nelson (D-FL) and Republican Gov. Rick Scott tied at 46 percent.

And a new Fox News poll showing Democrat Kyrsten Sinema and Republican Martha McSally also tied at tied at 46 percent in Arizona's U.S. Senate race.

And she reported on a Fox News poll showing Democratic Sen. Claire McCaskill and Republican Attorney General Josh Hawley tied at 45 percent in Missouri's U.S. Senate race.

Then she noted "the best of all of them."

"This is the Marquette University poll in that Wisconsin governor's race, it now not only shows a tie between Scott Walker (R) and Tony Evers (D), not only shows them with each having 47% of the vote, that Marquette University poll literally found the exact same number of humans picking Tony Evers as Scott Walker," she reported.

"It's not a statistical tie, a margin of error -- the exact same number of human respondents in that poll picked Tony Evers as picked Scott Walker," Maddow explained.
