Politics

In a country of dreamers and achievers, we seem surprisingly content in the middle.

The term "middle class" is at once useful for political purposes and practically useless as an economic descriptor. Without a consensus on an economic definition, nearly half of the country self-identifies as being in the middle class.

That gives politicians an opportunity to make far-reaching appeals to voters, speaking to Americans with incomes of $30,000 and $100,000 in the same breath.

It may be too little, too late for Rep. Todd Akin.

The Republican candidate for Senate from Missouri is seeing an influx of money in the closing days of his campaign. Still, it would come as a surprise to seasoned observers in the state if Democratic Sen. Claire McCaskill went down to defeat.

Both campaigns want to claim momentum heading into the final days of the campaign. This is especially true in battleground states like Iowa, where enthusiasm and voter turnout can make all the difference.

It's a common political metaphor — momentum — but is it a good one?

To many Americans, the right to vote in a presidential election is a sacred and precious opportunity. To others, the right to not vote is just as meaningful. And they exercise it.

In just-released data, the Pew Research Center reports that about 43 percent of Americans of voting age in 2008 didn't participate in the presidential election.

There are political races all over the country that aren't even close, but you wouldn't know it from listening to the candidates.

It seems that every behind-the-curve challenger is scrapping his or her way to victory and every ensconced incumbent is fighting an unexpectedly tight contest.

In the vast majority of pre-election polls, likely voters are usually asked, "If the election were held today, for whom would you vote?"

That's the wrong question to ask, says Justin Wolfers, a political economist with the University of Michigan. He's spent years researching polls, and in a new paper he offers what he says is the right question:

Who do you think will win?

President Obama and challenger Mitt Romney are making the most of every moment this weekend, with only three days left before Americans choose who will lead the government for the next four years.

Update at 4 p.m. ET. Focus Is On Early Voting:

On his first stop today in the final campaign sprint, President Obama was in the super-battleground state of Ohio. The AP reports that the president reminded voters that Tuesday's election is "not just a choice between two candidates or two parties, it's a choice between two different visions for America."

Dan Lungren has been in and out of public office since 1979. The Republican represented a Southern California district in the '80s, served as the state's attorney general for eight years, and then returned to Congress to represent the Sacramento area in 2004.

These days, he's still the same pro-business, limited-government conservative he's always been, Lungren told a friendly audience in the Sacramento suburb of Rancho Cordova.
