"Over the last few elections cycle, Americans have made a few things clear: They don't want the Obama agenda..."
Nonsense.
What 'few' election cycles would that be, they obviously don't include 2012, just two years ago, when the president comfortably won reelection and democrats expanded their majority in the Senate. The only thing made clear is that democrats do well during general elections when voter turnout is high (58.2 percent in 2012), and republicans do well during midterms when voter turnout is low (only 36.6 percent in 2014).
That republicans don't want the Obama agenda was already known before the midterms; when republicans consistently win general elections with a high voter turnout – and with a diverse voting population, not just republicans – then they'll know a majority of Americans approve of their agenda.
