Just in time for the Fourth of July weekend, a Harvard study confirms: Not only do Republicans celebrate Independence Day more intensively, but the celebrations, in turn, tend to solidify Republican beliefs.

The three key findings of those attending July 4th celebrations:

  • When done before the age of 18, it increases the likelihood of a youth identifying as a Republican by at least 2 percent.
  • It raises the likelihood that parade watchers will vote for a Republican candidate by 4 percent.
  • It boosts the likelihood a reveler will vote by about 1 percent and increases the chances they’ll make a political contribution by 3 percent.

What’s more, the impact isn’t fleeting. “Surprisingly, the estimates show that the impact on political preferences is permanent, with no evidence of the effects depreciating as individuals become older,”said the Harvard report.

Finally, the report suggests that if people are looking for a super-patriotic July 4th, [they] should head to Republican towns. “Republican adults celebrate Fourth of July more intensively in the first place.”

Looks like Republicans take seriously what Founding Father John Adams wrote after the drafting of the Declaration of Independence:

I am apt to believe that it will be celebrated, by succeeding Generations, as the great anniversary Festival. It ought to be commemorated, as the Day of Deliverance by solemn Acts of Devotion to God Almighty. It ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other from this Time forward forever more. You will think me transported with Enthusiasm but I am not. I am well aware of the Toil and Blood and Treasure, that it will cost Us to maintain this Declaration, and support and defend these States. Yet through all the Gloom I can see the Rays of ravishing Light and Glory. I can see that the End is more than worth all the Means. And that Posterity will tryumph in that Days Transaction, even altho We should rue it, which I trust in God We shall not.

Of course, Adams actually thought the “Anniversary Festival” would be celebrated July 2 — but the principle is the same.

Exit question: Why don’t Democrats like to celebrate the Declaration quite so much?
