What most liberals don't understand about the new GOP

I am constantly amazed at how little liberal pundits really understand the new far-right GOP. Every few days someone who is a lifelong Democrat complains that they don't understand how the GOP can reject things that just a few years ago they seemed to back. As someone who voted Republican for over 20 years, I think can explain their new stance. Now, I reject what this new GOP stands for, and I refuse to call them Republicans, but I think I can explain them.
Now there's always been a group of far right wingers that believed there should be little to no government. But I think there were 3 seminal events that caused the far right to become the main stream of the GOP, and the first and the last are obvious. To begin with, Fox News came into being. Before the proliferation of cable stations and their cable's explosion, the news came from the 3 major channels and PBS. This news was rather harmonious and took no sides. But now, the news is slanted by cable stations to suit the audience. And Fox News became the station that caters to and is watched by the far right. And unlike moderates and liberals, for the most part, conservatives get their news from one source, and that's Fox News.
And of course, the last event was the election of President Obama. For over 40 years, the GOP plan for each election was to lock up the white male vote, and to try to get enough votes from other groups with a stance of low taxes and a strong military to win national elections. So obviously, the election of a black man caused a shudder for most leaders of the GOP, and was at least part of the reason Mitch McConnell said that the number goal of the GOP in the Senate would be to make President Obama a one-term President. And how long did it take for the GOP leadership to see the the new President was too far left to work with? How many bills were passed before the GOP came up with this plan? No bills had been passed. As a matter of fact, this became the GOP plan before he had been sworn in. How early was this plan hatched? Late Tuesday night after the 2008 election. That's right, not 12 hours after the election.
But the second event is the one that everyone seems to forget about, and the most important to the rise of the far right in the GOP, and that would be hurricane Katrina. Katrina was an event that showed the left that George W. Bush was a failure as a President. To the left, George was the President that invaded a country for no logical reason, and Katrina showed them that President Bush and his administration was inept at home. But to the far right, Katrina proved to them that they had been right all along, that Government couldn't solve problems. Not that the government was inept, but that it was useless. And so the Tea Party was born after the 2008 election, not to change the government, but to dismantle it. And of course, this is just fine with those in the GOP who are proponents of big business, who see any taxes or regulation as a hindrance to their profit margin, and therefore need to be abolished. And this brought big money to campaigns that ousted moderate members of the GOP and brought the far right to the fore.
Take these 3 things, and it should be easy for liberals to see what happened to the GOP. But since most of them don't think of Katrina as a seminal event, but to the far right and the GOP, Katrina was a pivotal event, and one that helped set in motion the establishment of the new GOP, and the death of the Republican party in America..
