When I first conceived the idea for this article, I had only three “Killer B’s” in mind that I believed were going to be detrimental to Joe Biden’s presidential campaign.

Since then, former President Barack Obama has finally endorsed his old running mate for his old job. That endorsement added a fourth ‘Killer B” to the list — but more on that later.

The first “Killer B” I’ve identified are the “Bimbo eruptions.” That was a term made famous during the 1992 Democratic presidential primary when a series of women made infidelity allegations against then Arkansas Governor Bill Clinton.

Several women last year accused Biden of inappropriate touching and hair sniffing during his long Senate career, but of course, the allegations went nowhere as the media turned an expected blind eye.

In a bid for damage control, the Biden campaign released an apology video where Creepy Joe said the “boundaries of protecting personal space have been reset” and that he now “gets it.”

Now that Biden is the presumptive nominee with Barack Obama’s endorsement in hand, another more serious allegation against the former Vice President has recently surfaced.

It’s not a new allegation but the story from the accuser has become more lurid:

And I remember he–it happened all at once–the gym bag, I don’t know where it went. I handed it to him and it was gone. And then his hands were on me and underneath my clothes. And then he went–he went down my skirt and then up inside it. And he penetrated me with his fingers, whatever. And I–he was kissing me at the same time and he was saying something to me. He said several things and I can’t remember everything he said.

They say karma is a b*tch and that is especially true when it comes to politics. The Democratic Party opened up this can of worms during the Kavanaugh hearings when they set the dangerous precedent that a woman who accuses a man of sexual assault must be automatically believed — even when the only evidence is the accuser’s story.

The Second “Killer B” is the notoriously corrupt Ukrainian gas company Burisma. Readers of Red State are well aware of that scandal involving the former Vice President’s son Hunter Biden.

The Biden Family and campaign wants us to believe that a crackhead who was thrown out of the Navy for his drug abuse somehow landed a very lucrative seat on the board of a foreign natural gas company while his father was Vice President.

And to add insult to injury, Ukraine was in the former Vice President’s portfolio and area of responsibility. The public is not buying Hunter’s run of good fortune either.

Senator Lindsey Graham (R-SC) has initiated a Senate investigation of the Biden’s and Burisma and it is rumored that Attorney General Barr may be investigating as well.

The third “Killer B” is Joe Biden himself. Let’s face it, Joe Biden is a human gaffe machine who will undoubtedly keep the Trump Campaign and RNC ad-makers very busy this fall.

President Trump has called him low energy and his handlers are petrified to have him unscripted in front of cameras and microphones for too long.

Biden has flip-flopped during the campaign on major policy positions including the death penalty and “free college.” He is now against the death penalty and he was in favor of free college tuition as recently as 2015.

The “Fourth Killer B” is Barack Hussein Obama. President Obama won a historic election in 2008 and, of course, was reelected in 2012, but Obama’s historic presidency left absolutely no coattails for down-ballot and off-year Democratic candidates:

Truth to tell, Obama had ­already shown his feet of clay in 2009 in a series of endorsements that didn’t turn the tide for the candidates he stumped for. New Jersey Gov. Jon Corzine lost his reelection bid to Chris Christie, while Democratic gubernatorial candidate Creigh Deeds was blown out in Virginia. And a few months later, in 2010, Obama went all in for Arlen Specter in Pennsylvania — a deeply unpleasant Republican who had desperately gone Democrat because he had lost the confidence of his original party — only to see Specter lose . . . in the Democratic primary! (The guy who beat Specter then lost in November.) [W]hen voters went to the polls in 2014, Obama’s help availed Democrats nothing. Quite the opposite, in fact. Republicans took nine Senate seats away from Dems and gained complete control of Congress. By 2016, when Obama’s anointed successor Hillary Clinton lost to Donald Trump, the Democratic Party was in tatters. It wasn’t just the House and Senate the GOP came to dominate. Over the course of his presidency, more than 1,000 elected offices in the United States (out of 8,800 total) changed hands from Democrats to Republicans.

President Obama couldn’t get candidates elected while he was a sitting president, how much will his endorsement matter to Biden’s chances with Obama being four years removed from the White House? If the Biden campaign starts flailing, will the former President put his credibility and legacy on the line for his former subordinate?

A fifth “Bonus Killer B” are the so-called Bernie Bros, the rabid Sanders supporters who disrupt meetings and say they will not vote for Joe Biden under any circumstances. Twelve percent of Sanders supporters in 2016 voted for Donald Trump.

We will never – NEVER boost or support Joe Biden or defend his abysmal record and terrible policy positions,” Henry Williams, executive director of The Gravel Institute, told The Post. “We will tell people, as we always have, to vote their conscience and to make decisions based on the interests of all the world’s oppressed people … I do expect a massive exodus from the Democratic Party.

The “Killer B’s” will be swarming around the Biden Campaign like bees to honey. Will they be too much for the campaign to overcome? We shall see in November.
