It is hilarious to watch the flood of Republican officeholders head for the hills and discard Donald Trump like a piece of trash.

They are claiming that their sensibilities were so offended by Trump’s coarse comments about a married woman he knew, made eleven years ago, that they have no other choice.

To which I say bull****.

There is one reason and one reason alone they are bolting. They are looking at the polls and running scared.

More than 160 Republican leaders don't support Donald Trump. Here's when they reached their breaking point.

The NBC/Wall Street Journal poll showing an 11 point Clinton lead started a panic to match the ‘29 Wall Street crash. Trump might as well have had the word “unclean” emblazoned on his forehead.

They did not feel they needed to distance themselves when Trump called Mexicans rapists, called Vietnam hero John McCain no hero because he was captured, attacked an Ohio judge for having Mexican roots, sneered at a disabled reporter and slandered a dead war hero because his family was Muslim.

That was simply because the Trump polls were somehow staying up close to Hillary Clinton’s during that period.

Now that his support has collapsed and he is danger of finishing below the pathetic level of previous landslide losers like Barry Goldwater and George McGovern the rats are fleeing the ship.

No surprise they are led by Speaker Paul Ryan, who has impressed no one as a profile in courage during this crazy time. Ryan led from behind, failing to come out early and quickly against Trump, who from the beginning was a ticking time bomb for Republicans, set to explode at any moment with his message of hate and division.

Paul Ryan should spend more time on balancing the budget, jobs and illegal immigration and not waste his time on fighting Republican nominee

Now his campaign looks like it is imploding.

With the Republican majority in the House now in danger Ryan has acted and stated he will not campaign with Trump, though he has not withdrawn his endorsement.

He still seems to want it both ways and is learning that when you stand for nothing you fall for everything and Ryan now has Trump tied around his neck.

And the GOP may be heading for an historic defeat.

Republicans thinking that Trump's absurd performance was "good enough to stop the bleeding" is exactly why they're in this mess.
