Liberty Group/Tea Partiers better wake up. They are now the equivalent of the Nationalist Party in Nazi Germany, refusing to align against Hitler because they didn't like some of the positions of the Catholic Center Party.
By "this" I assume you mean the leftist power grab. I don't think that an inconsistent or even hypocritical approach is going to help.
Some politicians like Obama lie, and I don't want to copy that approach. The GOP has cost conservatives have too much power by not living up to conservative principles (spending in general and pork). Some GOP lawmakers put pork into the recent defense bill, when they had a great opportunity to set an example by not doing so.
At the same time, we should fight against the leftist evil with all our might.
