Since there's still a bit of mystery surrounding South Carolina Governor Mark Sanford's secret trip to South America, here's an open thread to discuss all of your theories.

UPDATE: he admitted to having an affair in his press conference today.

So what did you think of Obama's press conference yesterday? Maybe you were more struck by what Obama DIDN'T say compared to what he read from the teleprompter. For example, the Politico points out that his 55-minute news conference failed to include the words "Iraq" or "Afghanistan." That's not all, try the words "Korea," "Pakistan," "soldiers," "surge" and "war." No mention of the Army, Navy, Air Force and Marine. None of 'em. A stark difference from our previous president ... but I guess this is what Obama meant by "change you can believe in."

Anyway, I'll have my own shot at the questions. Yep, another Boortz Press Conference tomorrow at 11:05AM EST. And no ... I won't be using a teleprompter.

I got on a rant about unions again after reading about these government school teachers in New York. You know the ones sitting in these "rubber rooms" doing crossword puzzles and playing grab-ass? Yeah, those are the ones. What a joke. But you continue to turn your children over to the government to be educated.

Anyway, that got me thinking about how hideous unions are for this country, and I was reminded of a recent study by the Heritage Foundation. Take a look at some of the highlights below. It's wonderful stuff.

• Studies typically find that unionized companies earn profits between 10 percent and 15 percent lower than those of comparable non-union firms.
   
• Some unions win higher wages for their members, though many do not. But with these higher wages, unions bring less investment, fewer jobs, higher prices, and smaller 401(k) plans for everyone else.
   
• Final union contracts typically give workers group identities instead of treating them as individuals. Unions do not have the resources to monitor each worker's performance and tailor the contract accordingly. Even if they could, they would not want to do so. Unions want employees to view the union--not their individual achievements--as the source of their economic gains.
   
• Consequently, union contracts compress wages: They suppress the wages of more productive workers and raise the wages of the less competent. Unions redistribute wealth between workers.
   
• A better summary of the economic research is that unions do not increase workers' wages by nearly as much as they claim and that, at a number of companies, they do not raise wages at all.
   
• In essence, unions "tax" investments that corporations make, redistributing part of the return from these investments to their members. This makes undertaking a new investment less worthwhile. Companies respond to the union tax in the same way they respond to government taxes on investment--by investing less.
   
• Research shows that unions directly cause firms to reduce their investments. In fact, investment drops sharply after unions organize a company. One study found that unionizing reduces capital investment by 30 percent--the same effect as a 33 percentage point increase in the corporate tax rate
   
• The balance of economic research shows that unions do not just happen to organize firms with more layoffs and less job growth: They cause job losses. Most studies find that jobs drop at newly organized companies, with employment falling between 5 percent and 10 percent.

During his press conference yesterday, Barack Obama tried to articulate his position on government-run healthcare. Are you buying this?

Now we are getting stories of "brain drain" from companies like Citigroup and Bank of America. It was only a matter of time before the talented people realized the miracle of government.

Question: how many years did it take George Bush to run up the same budget deficit already reached by Barack Obama?

A $105.9 billion war-funding bill stuffed with all that pork Barack Obama said he was going to get rid of.

Obama wants to sign a UN treaty that says children have basic rights to education, health care and protection from abuse. Oh gawd.

Only government would spend $200,000 to promote ... tap water.

The ACLU is suing on behalf of two Muslim inmates in federal prison who say they aren't allowed to pray in groups as often as their peaceful, serene religion of Islam commands.

The Heritage Foundation believes that the CBO grossly underestimated the cost of this cap and trade bill. Here are the hairy details.
