Stick a fork in the Democrats and Republicans.
Wednesday night's latest round of deal making between President Donald Trump and Democratic congressional leaders is the latest evidence that the major political parties have lost all semblance of real power.
Never before have we seen the leadership of both major political parties so humbled. That power vacuum is currently enabling the president to act without any loyalty to his own party, while working with whomever he pleases on whatever issues he wants.
It's why we have a Republican congressional leadership, headlined by a Senate Majority Leader with an 18 percent approval rating in his own home state, that could not deliver on its party's seven-year-long promises to repeal and replace Obamacare.
And it's why the Democratic Party is getting more and more embarrassed as its highly-experienced-but-failed 2016 presidential nominee continues to weaken the brand by going on a national tour blaming everyone else for her election loss.
None of the above would have been possible before then-candidate Trump eviscerated a crowded field of 16 more experienced GOP regulars in the 2016 primaries. It wouldn't be possible before Senator Bernie Sanders, an independent who only registered as a Democrat months before the primaries, came extremely close to upsetting long-held party plans to nominate Hillary Clinton. (Now that same Senator Sanders is leading a march away from Democratic Party orthodoxy and fully advocating single payer health care, with a third of the Democrats in the Senate happily marching away with him.)
