It is Schumer and Pelosi who have led the most visual and verbal counterattack against the White House during this shutdown drama. Just to put the binary choice into 2018 terms, the shutdown had two basic rallying cries on the social media battleground. Democrat supporters and anti-Trumpers tagged their posts with the #TrumpShutdown hashtag, while Republicans and pro-Trumpers countered with #SchumerShutdown. Both of those hashtags were among the top trending topics on Twitter over the weekend.

That's when the news gets better for the president, a lot better. The latest poll of polls by the Huffington Post has Schumer's approval rating at a measly 26 percent, 13 points lower than President Trump. The same poll of polls has Pelosi's approval rating just a hair better at just under 29 percent. Perhaps the only other Democrat who came close to holding the floor on the shutdown as often as Schumer and Pelosi did was Illinois Sen. Dick Durbin, who holds an anemic 37 percent approval rating of his own.

With enemies like these, who needs friends?

On the Republican side, Senate Majority Leader Mitch McConnell also pales in comparison to Trump with a 21 percent approval rating, below Schumer and Pelosi. Paul Ryan is at 29.9 percent, just a hair above Pelosi. This too puts the president's supposedly disastrous polls into a more comprehensive light.

But the shutdown was just one example of how things aren't as bad for Trump as his weak approval numbers would have you believe. The entire landscape of American politics shifted even before he became president. Social media and the politically charged TV news channels have erased much of the traditional "honeymoon period" for new presidents. Even Barack Obama's presidential approval rating suffered a rare and steep decline of 18 percentage points from his inauguration to the one-year mark of his first term, from 67 percent to 49 percent.

The second factor just coming to the surface is the better-than-expected early positive effect from the tax reform law. The congressional Republicans are already starting to poll better on the shoulders of all the news of bonuses, raises and increased corporate investments in America. This is all happening before the lower tax withholding rates take effect in February and millions of Americans will potentially see a noticeable increase in their paychecks.

This doesn't mean Trump has slammed the Democrats into submission. His unpopularity is real and remains an inviting reason for dozens of potentially more popular opponents to enter the fray against him. But for now, Trump is lucky enough that his key opponents are named Pelosi and Schumer.

To put it in Mark Twain's terms, news of Donald Trump's political demise has been greatly exaggerated … again. But exaggerated takes on the president's poll numbers are the result of an incomplete look at the available data. Until more of the pundits take a more educated look at the full story, Trump will continue to surprise the "experts."
