So much for bipartisanship!

Less than 24 hours after sitting down with President Obama and pledging a new era of bipartisanship, Senate Minority Leader Mitch McConnell sent him an ultimatum signed by all Senate Republicans: “Until you give us tax cuts for millionaires, we will block any other legislation.”

It sounds like a Saturday Night Live skit, but that is, indeed, the new mantra of the party of, by and for plutocrats: “Tax cuts for millionaires — or else!”

Which not only shows how out of touch Republicans are with the American people, it proves they had no intention of trying to work in a bipartisan manner with  Obama on anything — not tax cuts, spending cuts, immigration, Don’t Ask Don’t Tell, the New Start treaty, extension of unemployment benefits, or anything else.

In fact, McConnell’s definition of bipartisanship is: You buy what my party wants. Period.

Well, maybe, at last, President Obama will learn a lesson. Stop being so nice to Senate Republicans. Stop thinking he can work with them. It should be obvious to him what became obvious to all the rest of us a long time ago: Republicans have only one goal. Mitch McConnell’s even admitted it. Their one goal is not to solve problems or cooperate with Obama. Their one goal is to destroy him politically.

So much for bipartisanship. It was born Tuesday. It died Wednesday.
