The Republican Presidential hopeful mistakenly calls his running mate the next U.S. president.

U.S. presidential hopeful, Mitt Romney, Saturday, unveiled state Congressman, Paul Ryan, as his running mate for the November presidential elections; but seemingly played into the hands of opponent, President Barack Obama, by erroneously introducing Mr. Ryan as the “next President of the United States.”.

No doubt, an Obama team that has upped its proficiency at pointing to the American voters, the campaign failings of the Republican candidate, will in the days ahead, cash in on a blunder that seemed needless.

Speaking after host governor of Virginia,MacDonald, at a brief event to introduce Mr. Ryan, the  Republican candidate told the small crowd mistakenly: “Join me in welcoming the next President of the United States.”

The crowd buzzed briefly, and just before Mr. Ryan’s speech, Mr. Romney returned, and explained that he “will be making a few mistakes now and again” and corrected that he meant Mr. Ryan is the next Vice president.

His choice, a member of the House of Representatives from Wisconsin, is viewed as inexperienced, but skilled economically. He chairs the House budget committee.

Mr. Romney’s campaign has centered on resuscitating America’s troubled economy that has seen high unemployment rate, and Mr. Ryan is expected to anchor that drive.

As a fiscal conservative, the Vice presidential hopeful will also excite the far right conservatives; and at 42, will also appeal to the American young, analysts say.

“Some people may disagree with Paul Ryan, but I don’t think there is anyone who will not respect his character and judgment,” Mr. Romney said.

Mr. Romney is known for advocating large cuts in spending and taxes.

“I will serve in a Romney administration to lead America back to prosperity and greatness,” Mr. Ryan said.

But the Obama campaign said in a statement that Mr. Romney’s choice stood for “flawed economic policies” that would repeat past mistakes.

“As a member of Congress, Ryan rubber-stamped the reckless Bush economic policies that exploded our deficit and crashed our economy,” Obama’s campaign manager, Jim Messina, said in a statement.
