One of the benefits of the Internet revolution has been access to free e-mail.  However, as we now know, the supposed "free" e-mail has come at a cost. As a believer in the free market, it is impossible to begrudge online companies their success, however, conservatives are sacrificing privacy and supporting liberal causes.

If you use a Gmail or Yahoo e-mail address and are pro-life, support gun rights and oppose ObamaCare, you are funding activities aimed at trashing your own beliefs.

Marissa Mayer, the newly minted CEO of Yahoo has “bundled” between $100,000 and $200,000 for Obama’s reelection campaign.  In other words, she went to her rich friends, collected a bundle of cash and sent it to the Obama campaign. AOL owns the Huffington Post. Where do you think they contribute their political dollars?

Companies like Yahoo, Google and Microsoft make a fortune selling all sorts of sensitive customer data to all kinds of companies that want to sell every imaginable good or service.

When a customer signs up for a free e-mail account and gives permission for their information to be sold, the proceeds of those transactions are often used to support the liberal political agenda of those companies and its executives.

For example, Forbes reported that Yahoo co-founder Jerry Yang recently contributed $30,400 to the Democratic Senatorial Committee in 2012.

The Center for Responsive Politics’ website OpenSecrets.org revealed that Yahoo! employees contributed more than $17,000 to Barack Obama’s 2012 reelection campaign compared to just $2,875 for Mitt Romney.

Google employees ponied up more than $263,000 for Obama’s 2012 campaign and $5,000 for Mitt Romney.  In 2008, Google’s political action committee, its employees and their families gave more than $800,000 to the Obama campaign. Following Obama’s victory, several Google executives put up $25,000 apiece for the Obama Inaugural Committee.

Microsoft employees contributed $362,742 to the Obama reelection campaign compared to just $82,000 for Romney.

In the 2012 election cycle, of the fifteen top members of Congress receiving contributions from Google, thirteen were Democrats. In fact, Google was the eighth biggest contributor to House Minority Leader Nancy Pelosi.

To be fair, these companies have affiliated political action committees (PACs) which also contribute to Republicans, but those contributions are far smaller than contributions to extreme liberals.

Conservative friends and associates are often surprised when I ask: “Why are you supporting liberal candidates and causes with your free e-mail?” They react with disbelief, but that is precisely what is happening.

We devised Reagan.com as an alternative to the big e-mail providers so customers will know that they are subsidizing candidates or causes with which they disagree, but so they may also feel that their private messages stay that way.

Reagan.com will never sell or otherwise divulge a customer’s contact information.

Today, the political system is obsessed with money: who has it, who can get it and how fast. Conservatives need to reevaluate where they are allowing money to be contributed.

The stakes of the presidential election are too high.  The left is doing everything possible to hold on to the White House. Before you hit the “send” button, think about where you are sending money.

Michael Reagan is the son of former President Ronald Reagan and the founder of Reagan.com.
