Are Republicans changing their tune about raising taxes?

When you think about raising taxes, which political party do you think of? For decades, Democrats have pushed to raise taxes. And Republicans refuse (and in many cases, make sure to point out that their opponents want higher taxes). But no matter what, whoever says there should be cuts to entitlement programs -- like Social Security -- has faced major attacks and pushback. Well now -- with Social Security funding getting critically low -- some Republicans seem open to the idea of raising taxes.
