Not everyone feels that way about Obama. However, it would seem that there ARE those who do. That is definitely a religious style hymn - sung about a presidential candidate.
Looks like those who ironically call Obama "the Messiah" to demean the attitude of liberal democrats toward their candidate are not that far off after all. It may be a minority, but there is proof positive of the messiah complex attitude.
And while I personally think Churches who fake speaking in tongues are way out in the parking lot outside of right field, there is a significant difference between a church leading children in praises for God and asking blessings on the president, and leading children in a religious-style hymn praising the president (or soon to be president) directly.
