Opposition research exists mostly in the political shadows. So perhaps it's fitting that this boot camp is in an generic conference room in a generic airport hotel outside of Washington, D.C.

It's run by private investigator Larry Zilliox, who specializes in opposition research. He allowed me to attend a session, but not to take pictures.

Zilliox is cagey about his clients: "As a general rule, it suits me best not to comment on who I've worked for. Everybody is better off that way."

The House voted overwhelmingly Thursday to approve a temporary measure to keep the government funded through the end of September. Government shutdown averted.

But it turns out the continuing resolution didn't just address spending. It contains six measures that limit how federal agencies deal with guns.

Wisconsin Rep. Paul Ryan's House GOP budget balances in a decade and re-shapes Medicare. That is, it would if the measure passed by the House on Thursday ever became law — which it won't.

Washington Sen. Patty Murray's Democratic budget raises almost $1 trillion in taxes by closing loopholes and adds $100 billion in new spending on infrastructure. But it won't become a reality, either.

The House has begun debate on its budget resolution, with a vote expected later this week. And as supporters talk about this budget, there's one comparison you hear a lot.

House Speaker John Boehner, R-Ohio: "Every family in America has to balance their budget. Washington should, too."

Rep. Scott Garrett, R-N.J.: "You know, every family in America understands the necessity of a balanced budget."

Budget Committee Chairman Paul Ryan, R-Wis.: "This is how every family tries to live in good times and in bad. Your government should do the same."

In the ongoing Washington budget battles, one word gets more of a workout than most: balanced.

This single word illustrates the vast distance between the parties. Democrats and Republicans are working from very different definitions of the term in discussing their budget proposals being unveiled this week.

What Democrats are saying: A balanced budget is deficit reduction through a mix of tax increases and spending cuts. As in: We want a balanced approach to reducing the deficit.
