Obama rips into Romney, Ryan on Medicare – UPI.com.

A campaigning President Obama in Iowa Wednesday slammed into presumptive Republican rival Mitt Romney on taxes and Medicare.

On his third day in the state, the president told a crowd in Dubuque, “The centerpiece of Governor Romney’s economic plan is a new $5 trillion tax cut — a lot of it going to the wealthiest Americans. Now, keep in mind, $5 trillion is a lot of money, even in Washington.”
