Washington (CNN) -- As Election Day gets closer, the rhetoric gets more intense, interesting and, shall we say, passionate. Here are some things you might have missed.
Blame it on biology
Researchers at the University of California and Harvard University say there's a genetic reason why some people just can't stand former Republican vice presidential candidate Sarah Palin.
Between a Reid and a hard place
The New York Times reports that Democratic Sen. Chuck Schumer -- the No. 2 Democrat in the Senate -- is finding himself in an "excruciatingly delicate position" as he works to keep Senate Majority Leader Harry Reid in office, while at the same time, weighing his own political ambitions.
After all, if Reid loses to Republican Sharron Angle and Democrats keep control of the Senate, Schumer is widely believed to be next in line.
Let the knives do the voting
AOL News wanted to find out if champion knife-thrower David Adamovich, known as "The Great Throwdini," could predict upcoming election races by throwing knives at candidates' names on a spinning wheel. Adamovich, a self-identified conservative, made some interesting picks.
Dog-gone it, they don't like me
Republicans, still upset at comedian Al Franken's stunning win to Norm Coleman in Minnesota's Senate race, are vowing to never let that happen again.
The Republican National Committee's No More Frankens site asks for donations in order to "stand together in 2010, to ensure that there will be No More Frankens."
Christine O'Donnell, the Tea Party-backed candidate for a Delaware Senate seat, has faced national scrutiny for campaign gaffes and controversial statements since jumping into the race. But she has taken it in stride and fought back hard each time. Perhaps she learned how to perform under pressure from her father, Daniel O'Donnell, an actor who once played Bozo the Clown.
Carl Paladino, the headline-grabbing Republican gubernatorial candidate in New York, is under fire for calling New York Democratic Sen. Kirsten Gillibrand "Schumer's little girl" -- a reference to her close friendship with the state's senior senator, Chuck Schumer.
Waiting 'til the last minute
Rep. Michele Bachmann isn't quite sure that Minority Leader John Boehner would make a great Speaker of the House if Republicans take back control after Election Day.
In a radio interview, the Minnesota Republican said she'd have to weigh all the candidates before her and would vote for Boehner if he were the only candidate running.
Photo of the day: What's in my drink?
Florida Democratic gubernatorial candidate Alex Sink seems a little unsure of taking a sip of her cafecito at a campaign stop at the Cuban Versailles restaurant Friday in Miami, Florida. Perhaps she got a text message warning her about it? Just joking. Check out the Getty Images photo.
Don't mess with Biden's hair
Comedian Jimmy Fallon took a cheap shot at Vice President Joe Biden's hair last night, joking:
"During a campaign stop in New York this week Joe Biden said to a volunteer, 'if I had your hair, I would have been president.' In response the guy was like, 'if I had your hair I wouldn't bring up the subject of hair.'"
