What would you call a "ringing endorsement"?

What would you call a "ringing endorsment" - lukewarm support?  Hey - wasn't me that picked Dylan's lyrics and message to indicate he was talking against those who would vote Obama only to have egg on their face because Dylan backs Obama.

I knew that would be the case even before I Googled to see if Dylan was backing anyone - I was THERE back in the days of Dylan coming on the scene and singing about Blowin in the Wind and The Times They are a Changing.

From the story:

His 1964 track 'The Times They are a-Changin' became the anthem for his generation, symbolising the era-defining social struggle against the establishment.

Now Bob Dylan - who could justifiably claim to be the architect of Barack Obama's 'change' catchphrase - has backed the Illinois senator to do for modern America what the generation before did in the 1960s.

In an exclusive interview with The Times, published today, Dylan gives a ringing endorsement to Mr Obama, the first ever black presidential candidate, claiming he is "redefining the nature of politics from the ground up".
