(CNN) New polling indicates that President Donald Trump does not have a winning option to get out of this partial government shutdown, and his position is deteriorating.

Let's start with the most important fact when it comes to gaming out the shutdown: the President is becoming more unpopular. His net approval rating (approval rating -- disapproval rating) in an average of polls before the shutdown was -10 points. It's now down to -14 points. That may not seem like a big drop but remember this is a president who has had among the most stable approval ratings on record.

Now, one move the President could decide to take to help his own standing is to push harder on the shutdown. Yet, the longer the shutdown goes, and the harder Trump has pushed his position, the more Americans are blaming him for it.

In a Quinnipiac University poll taken before the shutdown, 51% of voters said they'd blame the Republicans for the shutdown to 37% who said they'd blame the Democrats. A Quinnipiac poll conducted over the last week now puts Republican blame at 56% and Democratic blame at 36%. Put another way, voters are 5 points more likely to blame Republicans and 1 point less likely to blame Democrats for the shutdown than they were before the shutdown began.

It's not hard to make the connection that Trump's personal ratings are dropping because they increasingly see him responsible for the shutdown.
