“There’s been a dramatic zero-point shift in the polls since Obama came out for gay marriage,” tweeted Nate Silver on Monday.
The tweet wasn’t attached to a post or to a particular poll, but we can run some of the numbers on our own.
As it happens, today is the first day that all of the polls included in the Real Clear Politics head-to-head average were taken fully or mostly after May 9th, the day President Obama endorsed gay marriage.
As of this morning, they show Obama with a 1.7 percent lead. Looking back at the Wonkbook Dashboards, on the morning of May 9th, however, Obama had a 0.2 percent lead in the RCP head-to-head average.
So since coming out for gay marriage, his numbers have slightly improved.
