This is the problem with the GOP in a nutshell - they wouldn’t mind doing something to embarrass Obama or to make his poll numbers go down, but they lack the intelligence AND the balls to try to remove him - which is, of course, the only thing that matters.
Look at the Nixon affair. He had just been reelected with 61% of the popular vote and 520 electoral votes. If there was ever a President to be afraid of attacking, it was Nixon in 1973.
But the Democrats were methodical, they were highly organized and disciplined, they chose excellent faces (Ervin and Rodino), they never wavered, and they built their case brick by brick to fit a narrative so that, not only would Nixon’s landslide voters vanish but the country would turn around and elect the most radical leftist Congress since 1936.
Who among the Republicans can you imagine capable of pulling something like that off?
And it’s worse than that. If you shoot at the king, you’d better kill him, because there are no second chances in regicide. The diffuse, disorganized, leaderless GOP “investigations” will not only not succeed, they will lend credibility to the RAT narrative that it’s all partisan.
