Party Covention Scheduleing

I just saw this post at pro football talk, and what struck me was this line: "That adjustment happened because the Thursday night regular-season opener has been moved to Wednesday night, given the conflict with President Obama’s speech at the Democratic National Convention."

I recently heard that the Republican convention was shifting its speakers around because the television stations weren't going to broadcast many of them live when the RNC thought that they would.

And yet the NFL is changing its schedule to meet Obama's, instead of the other way around with the tv networks and Romney's speech.

Obama is the President,  but I wonder about the difference in response to the parties sometimes.
