Those causes are not being served when Senator Cruz undermines the election chances of the only political party that has any chance of undoing the disasters that Barack Obama has already inflicted on the nation and forestalling new disasters that are visible on the horizon.
Frankly, my opinion is that Sowell is suffering from a bad case of "GOPe Status Quo."
It pretty much makes me put him in the same column as a lot of other pundits from whom I really am not inclined to take any advice or counsel.
His fear is that the GOPe status quo will become the Democrate status quo, as in a rerun of 2008, after which the Dems ram through yet an Obamacare equivalent for a different sector of the economy.
