It seems to me, an outsider, even though I live in the Washington area, that Secretary Kathleen Sebelius stepped down, at least partially, because she was tired of dealing with the idiots in the Congressional Tea Party. These stupid and rabidly partisan members, especially in the House, showed her not an atom of respect. In hearings, they would use all of their time attacking the Affordable Care Act vociferously and mindlessly without regard to fact or reason. They were so ignorant and rude that, many times, they would not let her respond to their own questions. Secretary Sebelius would just have to sit there and listen to their rude, stupid, and ignorant verbal garbage.
The 1964 Civil Rights Act was one of the best pieces of legislation that the U.S.Congress ever passed and that a President ever signed into law. It is the overwhelming positive piece of the legacy of President Lyndon Johnson. It ended legal racial discrimination, the denial of access to public accommodations to people because of their race. It is still the law of the land because the property rights argument has never held water, when it comes to racial discrimination.
Former Florida Governor, Jeb Bush, President George W. Bush's younger brother, has never shown that keen an interest in being President of the United States, that drive that says you not only want the job but that you believe you are the most qualified person in the country to do the job. He would have several strikes against him in the eyes of the ignorant far-right in the GOP (see above), immigration, education, civil rights, common sense, etc. He's simply not dumb enough to be a member of that part of the party. I don't see how he could win the GOP nomination and he seems to know this. He appears to be very reluctant to walk into the weed-whacker of the Tea Party's ignorance, stupidity and bigotry. This is good for the Democrats and bad for the GOP (Thank you Richard Nixon for your southern strategy) because he would be far and away their best and most qualified candidate for president.
