'Donald Trump is disgusting' appears in the sky above Rose Bowl

Sad that Trump's opponents feel the need to resort to personal attacks.

Yes, how sad indeed.
Trump has never resorted to personal attacks.

How many times does it have to be said?

You can't Stump the Trump.

So the party should concede the nomination to him to satisfy your desires for a hilldawg landslide? Nice try, not happening.

It may not be happening, but the cost to the GOP Establishment of Trump "not happening" is rising by the hour.

That might be true.
But the cost to the entire Republican Party "not happening" in the general election, "is rising by the hour" as Trump continues to increase his chances of being the Pub candidate.

This will persuade precisely zero voters.

It is in California, which isn;t going to vote for Trump in the general election anyway and usually figures in late in the primaries.

The message was shown above and during the Rose Parade.
This Parade not only had nation-wide TV coverage, but the parade is also shown to viewers world-wide.
The message surely has some effect. As it reminds people of Trumps "disgusting" bigotry and hatred for many groups of people in the USA.
