I didn't leave the Republican Party. The Republican Party left me.

Okay. Let's get this straight.

For 5 years (2009 - 2014) the GOP said "Oh, we just don't have enough influence to do anything." At first there was some truth to that- minorities in both houses of Congress, and a Dem President will do that. Even so, they seemed unwilling to use what influence they did have, because the MFM would call them big meanies. 

Porkuluous passed with nary a word.  ObamaCare could have been derailed at any of several points, but Republicans wouldn't.  At one point it could have been killed in committee.  At any number of points it could have been killed by a single Republican refusing "unanimous consent" to skip the reading of the bill (or the various amendments). 

Then Scott Brown was elected as the "41st Vote Against ObamaCare."  All Republicans had to do to kill it was keep the debate moving until he could be sat.  Instead, they allowed it to be passed because they didn't want to work over Christmas.

Then, 2010, we handed them the House. With which they immediately preceded to do... nothing much. "1/2 of 1/3 of Government!" we were told. "Oh, a Shutdown would ruin our chances in 2014!" we were told. (Hmm... almost as if winning elections were more important to them than doing the right thing)

Did they even pass a budget?  No.  "Oh, it will just get stopped in the Senate."  So Continuing Resolution after Continuing Resolution passed.  Did they stop raising the debt ceiling, or even get some kind of real budget cut in return for raising it?  No.  In fact, they ceded that power to the President, just so no one would ask them to do something scary like vote on it again.

So in 2012 (after 2 years of them doing nothing, and with a candidate who couldn't/wouldn't take on TFG) we let them maintain their control of the house. For another 2 years they proceeded to do... not much. 

Admittedly, after Mitt Romney's loss in 2012, they were a somewhat reduced party.  Lots of soul-searching had to be done.  But they still had chances.  The shut down was the most intestinal fortitude any Republican had shown in years, and the leadership fell over themselves to end it, and give up yet more concessions in the process.  Only their (stated, though not acted upon) opposition to ObamaCare saved them.

Now in 2014 we have given them majorities in both houses of Congress. So rather than stall until the new congress can be sat of course they rush to pass a bill which takes away almost all of the influence they would be able to wield for nearly half (and really more than that, considering we'll be spinning up for 2016 at the end of 2015) of the next Congressional term.

Why should I ever vote Republican (for national office) again?
