Republicans must realize that now is the time to make the change. It cannot wait until 2016 when they have a chance to take the White House. During these last two years, they need to show what their plan for America and pass as much legislation as they can. Sure, President Obama may veto it. There is nothing they can do about that. However, they can show America where they want the country to go and build upon in 2016.
In particular, legislation should be passed to reform the tax code, secure our borders, and pass a bill for the keystone pipeline. While Obama may veto all of these, if they come together they can get a 2/3 majority and pass them over his veto.
The key point is this: Don't celebrate yet. There is much to be done, and now is the opportunity to do it. Mitch McConell and John Boehner have the opportunity for greatness, will they capitalize? We will see.
