Pretty Sure I'm Not.
The NFL absolutely crushes the NCAA in terms of popularity among US residents by nearly 20%.
And of those 52% or so who are actually fans to ANY extent (vs. those that don't give a shit about it) only 22% would even be concerned if there was a conflict. Those who watch "a little bit" or virtually not at all wouldn't care. That's about...oh, 80% of the country.
Daylight savings time was standard for decades- until they moved it. people got over it.
I'm not opposed to making tuesday a federal holiday, but the conservative argument is that more federal holidays costs business money. The saturday option alleviates that.
