ELKHART, Indiana (CNN) - The Obama traveling press corps arrived at its hotel Tuesday night to find not only their room keys waiting on a table in the lobby but white packages containing 'Obama Energy Plan' tire gauges.
"Happy Birthday, Barack Obama," read the note that came in the package from the Republican National Committee in Washington, D.C. "In celebration of Barack Obama's special day, the RNC is sending you an important gift in his honor."
It then quotes Obama's contention that properly inflated tires would save as much energy as could be gained by increased drilling.
"Instead of actually increasing America's domestic oil supply, this is how Obama thinks you should try to alleviate your pain at the pump," the note ends, with "best wishes" from the RNC.
The gauges were sent to producers from the five major TV networks and most print reporters. They came in several colors, including gold, blue and green.
Upon seeing the gauges, Obama spokeswoman Linda Douglass said, "You can use it to check all the hot air coming out of [McCain's] Straight Talk Express.
A senior adviser handed out gauges on McCain's campaign plane and they were passed out outside Obama's energy speech in Lansing, Michigan, on Monday.
"They think it's funny that they're making fun of something that is actually true," Obama said Tuesday in Ohio. "They need to do their homework."
