If the only bad thing that happened to Donald Trump this week was that his campaign manager was charged with battery after grabbing a reporter at a campaign event last month in Florida, he might have escaped this "honor."

After all, Trump insisted that Corey Lewandowski, the manager in question, had never even touched the reporter -- and that Michelle Fields, the reporter in question, had been bothering him and had made up what actually happened on that day at the Trump National golf course. Trump, said Trump, was the one who was the victim here!

Yes, in the normal world of politics, your campaign manager being charged with battery would be bad. And not only refusing to fire him but going on the attack against the female reporter who had been grabbed would have been really, really bad. But, this is Donald Trump we're talking about. He has turned every piece of political conventional wisdom on its head -- so why not this one too?

Then came Trump's town hall interview with MSNBC's Chris Matthews on Wednesday. And that's when his week went from just bad to horribly awful.

Trump made a basic mistake: He indulged Matthews on a hypothetical scenario under which abortion was made illegal but women still sought them out. What should be done to those women, Matthews asked. And asked.

"The answer is that there has to be some form of punishment," Trump eventually responded.

And, boom goes the dynamite.

Abortion rightsgroups went wild. Antiabortion groups went wild. Trump's opponents -- Democrats and Republicans -- pounced.

And even Trump, the man who won't apologize ever for anything, suddenly found himself in clarification mode. He issued one statement saying that the issue should be left to the states. He then issued another insisting that the woman seeking the abortion shouldn't ever be punished but the health care provider doing the procedure should. It was a classic attempt to clean up a bad political spill. (That, in and of itself, was weird -- Trump backpedaling like every other cornered pol.)

Amid all of that mishigas came two more body blows -- made all the worse because they were in the form of Trump's favorite thing in the world: Polls.

First came a Marquette Law School survey that put Ted Cruz at 40 percent to 30 percent for Trump and 21 percent for John Kasich in advance of Tuesday's Wisconsin primary. Then a Fox Business poll put Cruz at 42 percent to 32 percent for Trump and 19 percent for Kasich.

For a man who thrives on winning, not only was this week a loss but, if the polls are right, next week will be one too.

Sad!
