There is a subtle difference between wanting the president to fail and expecting that one to fail, and some people are missing that difference. I and other
PUMAs do not want that one to fail, because his failure means more trouble for our country...and lord knows our country has seen enough trouble to last a lifetime. But we expect him to fail, because we saw right from the beginning that he was nowhere near experienced enough to take over the leadership of this country right now. We are not surprised when he blunders and stumbles. We are not shocked when he goes back on his word. We saw this pattern of his when we checked his near-nonexistent political record and watched his behavior during the democratic primaries. It would be great for our country if he did not fail, but we think his success is about as likely as the Loch Ness monster being real. :-)
That is why we did not support him, in the first place.
Furthermore, PUMAs banding together in support of him (even when we have no reason to believe in him) will not help him succeed. Our support of or opposition to him does not affect his abilities or the lack thereof. The only way for him to succeed is for him to be competent in the first place. Blaming PUMAs or Republicans or anyone other than him for his lack of performance is making excuses. If he succeeds or fails, it will be because of him, not because of anyone else.
