After spending millions of dollars in the presidential and Senate campaigns with little to show for it, many superPACs and other outside groups are still tending their wounds. But it's too soon to write off superPACs as a waste of wealthy donors' money.

Consider, for instance, this upset in a congressional race outside Los Angeles.

Debate over the long-term debt and the annual deficit has dominated the post-election agenda. Both the White House and Congress want to avert massive budget cuts and tax hikes early next year, a situation popularly called the "fiscal cliff."

The challenge has been brewing for years. But its current prominence owes much to the decades-long lobbying of billionaire Peter G. Peterson and his private foundation.

Political observers are still working through the rubble of the unprecedented $6 billion presidential campaign, but we're getting a steady stream of reaction and analysis.

The liberal advocacy groups U.S. PIRG and Demos have one of the most striking numerical comparisons: 1.4 million to 61.

A "return on investment" is a concept better known to Wall Street than to Washington. But after President Obama and the Democrats won most of the close elections last week there are questions about the seven- and eight-figure "investments" made by dozens of conservative donors.

During the election season, it was pretty common to hear about donors making "investments" in superPACs and other outside groups, rather than a "political contribution," perhaps because the phrase has a sort of taint to it.

This presidential election attracted $1.5 billion in outside spending — TV ads, robocalls and other political activity by groups created to take advantage of the new rules of campaign finance law.

On the day after the voting, the track record of the groups, most of them conservative, is open to question.

Tuesday night was a rough one for Karl Rove. The GOP guru is the guiding light and chief fundraiser for the biggest outside spender: the twin groups American Crossroads and Crossroads GPS.

The battle to control the Senate was a proving ground for the new Citizens United politics. Outside groups unleashed heavily funded barrages of attack ads meant to help elect candidates while letting them keep their distance from the nastiness.

In Ohio and Virginia, the tactic failed in rather dramatic ways, as Republicans backed by secretly financed ads failed to beat seemingly vulnerable Democrats.

As relentlessly as the candidates have courted voters, they've also shown their love to donors.

A report by the Center for Responsive Politics places the total cost of the 2012 elections at an estimated $6 billion, which would make it the most expensive election in U.S. history

If you're using social media to follow the presidential campaign or even if you're related to someone else who's doing that, there's a good chance your cellphone got spammed Tuesday night with an anti-Obama text message.

The messages went out between 7:30 and 10 p.m. They were anonymous but quickly traced to a Republican consulting firm in Northern Virginia.
