Think Progress describes it:
Republicans have consistently denounced President Obama’s plan to allow the Bush tax cuts on income over $250,000 to expire at the end of the year. “We ought not raise taxes on anyone at the end of the year,” Senate Minority Leader Mitch McConnell (R-KY) has said of the Obama plan, which would raise taxes on roughly 2.1 million high-income earners (while still preserving a piece of the tax cut for them).
A new Senate GOP tax plan released by McConnell and Utah Sen. Orrin Hatch (R), however, raises taxes on nearly 10 times as many Americans by allowing certain tax breaks signed into law by President Obama expire at the end of the year. Putting an end to those three tax breaks — the Child Tax Credit, a tax break on college tuition, and a more generous Earned Income Tax Credit — would raise taxes on 20 million families.
I know the teabaggers won't accept it (because they don't seem to live in the real world of facts), but this is just further proof that the Republican Party cares only for the rich. Raising taxes on the rich is anathema to them, but they don't mind raising taxes on middle class Americans at all. I just don't understand why anyone who is not rich could even consider voting for a Republican.
