Monday in politics: Obama, Romney prep for second debate, and more

President Barack Obama and Mitt Romney will remain hunkered down Monday prepping for the second presidential debate, which is 9 p.m. EDT Tuesday.

Obama's mission is to turn around what was widely panned as a lackluster performance in the first debate and be more aggressive and less "polite."

Romney's mission is to come out the winner of this debate, too, and maintain the momentum he has enjoyed since the first face-to-face clash with Obama.

The race remains squeaky close, according to the latest ABC News/Washington Post poll. Likely voters split 49-46 percent between Obama and Romney if the election were today. That compares with 49-47 percent in the ABC/Post poll conducted just before the first debate. The three-point difference between the candidates in the latest poll is within margin of error.

Also worth noting Monday: Paul Ryan campaigns in his home state of Wisconsin and Ohio; Ann Romney campaigns in Pennsylvania; and first lady Michelle Obama stumps in Ohio.

And then there is this: Tuesday's presidential debate will take place exactly three weeks before the election.
