Obama will travel to seven. Romney, to five. And this razor thin race got even closer. Every night we'll bring you a brand-new abc news/"washington post" poll and tonight the candidates are separated. Look at this. Just 0.07%. That's about 91,000 people out of an estimated 140 voters in this country. 14 days to go. It's "your voice, your vote" and abc's david muir is in the middle of the action in the swing state of colorado. David? Reporter: Diane, good evening from the rockies.

Mistaking off from florida flying west to nevada tonight here in colorado, tomorrow back into nevada, iowa and thursday, ohio. President obama fueled by his final debate performance with a blistering attack on what he calls romney's shifting positions. That condition he jokingly calls romnesia. We joke about romnesia but this is important. This is about trust. You know, there is no more serious issue in a presidential campaign than trust. Reporter: It's romney in a race to the finish too looking to build on the continued momentum from the first debate firing back at the president. He's been reduced to try to defend characters on "sesame street" and word games of various kinds and then misfired attacks after one another, you know, the truth is that attacks on me are not an agenda. Reporter: Both campaigns trying to reach the sliver of undecideds voters left with very targeted data. The obama campaign with a smartphone app hoping supporters will download it revealing which neighbors the campaign believes could be potential supporters. In fact, as we stand right hire in this denver neighborhood on that obama application we downloaded in this neighborhood there are 12 flag, 12 doors they hope supporters will knock on. We decided to test the first name on the list. So you're lawrence. You're 75 years old. I go by larry, yeah. Reporter: You go by larry. The application has it right. Larry told us he has no problem the name is on the list but he says it doesn't matter. He voted early. Both campaigns going high tech this year, in fact, the romney campaign says they've knocked on more than 9 million doors, made three times more phone calls THAN the McCain made four years ago and will add one more state to the list for president adding california to the list andtape jay leno and mtv trying to reach young voters so revved up four years ago as they race to it.
