Obama maintains lead, but Romney within striking distance

On the eve of the first presidential debate, President Barack Obama maintains his national lead over Mitt Romney, but the Republican nominee is well within striking distance, according to the latest NBC News/Wall Street Journal poll. …

For Obama, he’s ahead at a time of growing optimism about the economy and nation’s direction. For Romney, it’s a “margin of error” contest that comes as interest in the upcoming election lags among key Democratic constituencies versus four years ago. [cont.]
