CHARLOTTE, N.C. - Virginia Senate candidate Tim Kaine gave a powerful endorsement of President Obama at the opening of the Democratic National Convention Tuesday night and predicted that the gritty nation had a bright future, declaring, "tough times don't last, tough people do."

Sound familiar? It should. Because just last week, at the Republican National Convention, country giant Trace Adkins introduced a brand new song about the gritty nation coming back. It's been adopted as the unofficial GOP theme song.

Adkins sang: "Tough times don't last, tough people do." Naturally, the song is titled "Tough people do."

Said Kaine: "We've been through tough times, but we're tough people. Tough times don't last. Tough people do. Let's come together, show how tough we are and prove our best days will always be ahead of us."

No mention of Adkins or his song, though.

It is unclear if he knew of the song or not, but an aide tweeted that the former Virginia governor "is our best speechwriter by a mile" and tinkered with it even as he headed to the podium.
