A Republican majority in the Senate, which now seems all but certain, will not change anything substantive in terms of national policy. It will simply give Senate Republicans a more prominent platform on which to engage in the sort of meaningless political posturing which is now almost the whole business of the House.
Extremist legislation with no chance of ever passing will make its way to the Senate floor, where it will be killed by Democratic filibusters. Ted Cruz, who is actually a fairly intelligent man, will probably squander the opportunity to critique Obama’s policies through investigative committees in favor of his fatal addiction to cynical and irresponsible demagoguery.
Rand Paul will probably not be allowed to mount a meaningful offensive against Obama’s Constitutional crimes, because most Republicans endorse them.
Progressives might take heart at the idea of the Republican clowns having a brighter spotlight in which to disgrace themselves — but they’d be wrong to do so. Two years of a Senate led by the clownish McConnell and the cynical Cruz will make Obama look good by comparison, and pave the way for the easy Presidential victory of another Democratic spokes-model for the plutocracy like Hillary Clinton.
The prospect of a clownish, impotent Congress and another corporate lapdog in the White House is what keeps the champagne flowing on Wall Street and lets the 1% sleep peacefully at night.
